I am 7 weeks pregnant. Very nervous as several previous miscarriages. But felt positive because blood tests looked good and had ultrasound showing fetus is correct length and saw heartbeat. Then out of the blue I had very sharp abdominal stabbing pains and started bleeding bright red blood. I passed a thick tissue mass, about 5cm x 6cm. Then a lot more blood and started having painful cramping at intervals. I bled a lot for several hours with very bad pain. I was absolutely sure I had miscarried and when the doctor saw the tissue mass I had passed and how much blood she also told me she believed I had miscarried. I was surprised that there was no bleeding overnight. I had ultrasound this morning and was flabbergasted to see the fetus is still there and heartbeat still visible. I now haven't bled for 24 hours, but I have some stomach pain. I really don't know if I can hope that I will now continue with a healthy pregnancy or if I should prepare myself for the worst. Has anyone had a pregnancy survive such an early huge bleed? I feel so scared and confused. No one could explain why I bled or what the tissue mass was (definitely was not pregnant with twins). Thanks for listening! Going crazy trying to remain calm and just wait it out.
