Hello. An thankyou for sharing your pain. I fully understand your situation. I went through a similar situation also. I went for a scan at 3 months just finding out that I was pregnant. I had severe cramps in my lower back and stomach with tightening also. Not until I complained to my gp. I was referred for a scan an was told I was three months pregnant with twins. I looked at them like they were mad because I had a full blown heavy clotting nearly 9 days or more period. There is no way I could be pregnant. They said it's most common to bleed whilst pregnant. I said I no this already from previous pregnancy but not clots and bleeding like a tap that's not possible. There answer was no its not known to bleed like that an still be pregnant.
Well I was pregnant now with twins. One had nor formed up to speed with the other which was showing three months where as the other was showing 6 weeks.
After a week the babies heart beat had stopped. There advice to me was that your baby has died an will most likely pass out of you an might take the other baby to. Well this cut my soul so much but I didn't except that it was going to happen and went home an prayed that God would sustain my pregnancy.
6 months later my baby girl was born very healthy and strong. Her twin decided to absorb back into me.
I believe I had triplets with the blood loss at the beginning of my pregnancy. Then it became twins. Then a singleton.
Do my baby girl survived although I had so much going on.
Keep positive. An I wish you well.
