Update...hello just wanted to let you know that at 6 weeks my levels were 15000 and got ultrasound and saw only one little bean so I guess I'm just bloated from all the eating lol. I'm still really bloated but today I started taking progesterone pills the doctor prescribed and feeling a little better I'm not sure if the bloating was due to low progesterone so maybe my stomach will go down tomorrow.
I had a lot of bloating in the beginning with my twins, but mine was due to IVF treatments & my ovaries still being a little stimulated from egg retrieval.
p.s. I couldn't fit in my pants at 5 weeks either :)
have you already had your bloodtest to confirm and if so, what were your HCG levels? Mine with twins at 6 weeks was 93,000. Also my Dr. does a confirming scan at about 6-7 weeks and that's how I found out I am pregnant with twins (same appt. I found out my levels, had I known before I would have had a suspicion!) Good Luck!
