I just had a natural miscarriage 2 weeks ago. I bled for about 7 days and after it stopped my Husband and I have been sexually active ever since. Last week I started feeling heart burn, acid in my stomach, headaches, minor cramps on my lower obdomen and sharp pain on my breasts. All the same symptoms that I felt in the first few weeks of my previous pregancy. Could I have gotten pregnant again so fast?? Last week I did a urin pregnancy test to check if my HCG level has lowered from the other pregnancy, and I got a negative. I did an ultrasound last week to check my uterus and my ovaries and everything was fine and clean. So is it possible that I got pregnant so fast?
