Just found out I'm pregnant,I've done 4 hag tests(first was 59,then 2 days later it was 62,then 2 days later stayed at 62,then 2 days later it went to 59) I went to ER and they didn't see anything! Nothing in uterus,Fallopian tubes,ovaries,or even thickening of the uterine wall! What is going on? Could I still be too early in my pregnancy? Why hasn't my uterine wall thickened since obviously I am pregnant? Please help!!
