Hello! Currently pregnant and scared. This is my 7th pregnancy.After having 5 miscarriages when finding out i had a positive i was so scared. I went to my ob and they werent able to find anything thru vaginal US but with blood work it was confirmed. Yesterday morning i started bleeding. Like a menstrual cycle no cramping. I was fearing the worst again but when I went to see my ob that afternoon they found a heart beat!.doctor said everything looks fine and all we can do is wait. She also started me on a low dose of asprin and asked to come back in 3 weeks. Has this happened to anyone?
