I had the same uncomfortble stretching feeling you're describing. Then my back hurt, and my skin broke out really badly (I looked like I had chicken pox!) Then I had more severe pain. When I went into the doctor's I was definitely prego. At 19 days past ovulation I had an HCG of 970. No surpirse to me, I know when my face broke out and I started smelling every little thing.
Sounds like a good sign to me! I will cross my fingers for you. My first two signs (prior to BFP) were: a zit (I never get them, I usually just get a red bump on my face every month, but no true zits) and my hands and feet kept falling asleep. Good luck! I hope it's your month!
I also had heartburn days before a positive test. My other early symptom was a dry mouth with a funny metallic taste.
I had reeeeeeeally bad heartburn with both of my pregnancies- even before I found out I was pregnant!
suegre (that means luck, right?)- I hope you are...how many dpo are you?
Had you ever experienced heartburn before you were pregnant?
I had terrible heartburn before confirming my pregnancy test!! It only lasted a few days and havent' had it so bad anymore...
