Extreme fatigue, muscle weakness & rapid heartbeat, 33 weeks. Is this normal?

[AHP84]

I was just wondering if anyone else in their 3rd trimester is feeling this way. I honestly can't remember from my last pregnancy if I experienced feeling this extreme exhaustion, muscle weakness, and shortness of breath to the point where I feel like I'm suffocating. The only thing I do remember from my last pregnancy was the rapid heartbeat and arythmia, which brought on dizzyness and weakness, but in this pregnancy, it's a little different when it comes to the rapid heatbeat.
I have a CONSTANT feeling of extreme muscle weakness, even when I'm completely relaxed and resting. My muscles all over my body feel like I've done a workout beyond my ability; they have that tightness and weakness you feel if, for example, you were to do push-ups, sit-ups, squats, pull-ups, jump rope, and run a mile in a matter of minutes. Sometimes I feel like I can't even lift my legs for what little it takes to put one foot in front of the other to walk, and my stomach muscles are so drained that can't even take in a deep breath, it feels as if I have no strength in my arms to even lift them, and my heart beats so rapidly and pounds so hard in my chest that I can feel my pulse in my head and behind my eyes. It's horrible. It's getting worse by the day.
As long as I'm sitting still or lying in a reclined position, I feel just a little bit better. The weakness and exhaustion is more bearable, anyway. But as soon as I'm up and moving around even to so much as go to the bathroom, it feels like I have to run half a marathon. It's absolutely miserable. I feel so out of shape and weak.
Am I lacking a vitamin or mineral in my diet? Or could there be something wrong?
I see my OB next Tuesday. I haven't mentioned this to her yet because it's only gotten this bad in the last week, at least to where it's a constant feeling. Before last week, it was occasional and I figured it was nothing out of the ordinary. But now I feel like I can hardly function because I just feel so weak. Anyway, I just called my OB clinic and I'm waiting on a call back from the nurse there.
I just wanted to know if anyone else was/is in the same boat?

I experienced weakness during my entire pregnancy. Especially my legs and arms. Insomnia, fast heart rate and palpitations. I was hoping that after my baby arrived, all these dreadful symptoms would go away but they didn't. I eventually discovered, on my own through research and trial & error, that I had a magnesium deficiency. When magnesium levels are low, it's likely that your potassium levels are low as well. These 2 minerals are very essential, especially during pregnancy. And a deficiency in either will cause all the symptoms mentioned, plus many more. Try increasing your magnesium and potassium intake.

Hey! I have the same extreme loss of breath and the heart beat thing. My OB actually sent me to a heart doctor. He ran some tests and found out a have an irregular heart beat and.. something I can't remember. I went a couple times to make sure I didn't need life long medication or help during labor. He said I've probably had it my whole life but my heart is closer to my head now that my baby is pushing everything out of his way. He says I will be fine. I just hear and feel it bc my heart is higher. U could have the same thing going on. I would think u would be okay to wait until u see ur OB and they can send u to a heart specialist. But its real..

I'm almost 34 weeks pregnant and I feel EXACTLY as the APH84 felt back in 2009. The last week and a half I have felt like the life has been sucked out me. Before that, I was up and doing a lot around the house, projects, cleaning, just always busy with something and I was happy.  Now just even typing this strains my muscles. I feel extremely exhausted, rapid heart beat, severely out of breath to the point where if i'm standing, I need to lean down on a counter with both arms and put me head down. I;ll be standing and all of the sudden I feel dizzy and that I need to go lay down or else I'll faint.  my muscles feel like I worked out very hard even when i'm laying in bed.  I have a hard time catching my breath just sitting there.  I'm starting to get really worried.  I just got diagnosed with gestation diabetes about 2 weeks ago so i'm monitoring that as well.  It's not bad though, i was only 3 points above the standard limits kaiser has. the diet is hard and I havent been eating as much as I used to since I was really in love with fruit, juices, yogurts and things with carbs in them. i have an appointment next thursday so i'll see what my ob says.  i've been really nervous and all this laying around is really boring with way too much time to think and search the internet.  I couldnt believe my eyes when i read the first post, it's like i had written that.  If there is anyone else out feeling this way, please post. I just posted because i think it really helps other women not feel so isolated and scared.  I'll write again after i talk with my Ob.

OMG ... Ive been feeling all of these things... my O.b. doctor just checked the strength in my arms and told me that i hadnt had a stroke... I can even wash a dang spoon! My mom and my health nurse think it might possibly be an iron deficiancy but i can take pills. pregnant women appearently need 27mg's of iron aday... thats like 4 days worth of only spinach! If I am low on iron i can see why... i havent been eating much foods with iron in them since i was 4 months pregnant... im now 8! Im getting kinda scared because i dont want to be with weak for labour! my symptoms also come with suddenly feeling like im over heating and sweating with the truck window fully down and cold wind blowing in my face! Its rather disturbing to not know whats going on and my own O.B. doctor just tells me oh its nothing u didny have a stroke ur fine, meanwhile i feel like im watching the life be sucked out of me more and more each day!   I hope its not pre-term labour.. :O I just wanna have my strength back and have this baby! :(
