My last period started on March 18. I took a pregnancy test on April 29 and it came back positive, that same night I started what I thought was a miscarraige-strong cramps, lots of bleeding with lots of tissue and clots. This lasted about 6 days. On May 18, I took another pregnancy test to make sure it was negative, and it came back positive. I thought maybe I had leftover tissue inside my uterus so I went to have an ultrasound on May 23. There was a gestational sac measuring 5w1d (based on my last period I should be 9w) followed by a negative urine test. Today, May 25, I took another at home pregnancy test and got a positive. Has anyone else experienced anything like this? I have no pregnancy symptoms, I was told my cervix is still open.
I am desperate for help and/or answers as to what is going on. Is it possible (normal) to have my ultrasound and expected be four weeks off?
