My LMP was 3/13 and according to my ovulation kit i ovulated on 3/31. I got a positive HPT on 4/15. I started cramping severely on Fri. 4/24 and lightly spotting when i went pee, I went to the ER on Fri. and the doc said that my blookwork and urine samples said that i was pregnant but that my ultrasound did not. My Hcg levels were only 340 on friday, my cramping got consistently worse today so i went to my doc and she did more bloodwork which we will have the results on tomorrow but the ultrasound she did didn't show anything either, she said it could just be too early to tell but i don't anyone else whose ultrasound didnt show anything at this stage, has anyone else had a similar situation? Please Help!!!
