Hello everyone! I did a test as soon as there was a delay, showed two lines. After some time, I did it again and it was still two lines. I went for an ultrasound, the term was about 9 weeks, but the doctor didn't see anything, he said to come back in 10 days. On the 26th, my stomach started hurting badly, and there were discharge first, then brownish, now brown. For three days, my stomach hurt, now it seems okay, but there are discharge. Has anyone experienced something like this?
