This is my first pregnancy. I am super paranoid and worried wondering if my baby is okay. Im 5w exactly today. I am scared to have 2nd scan. Im afraid that i may not see and hear my baby's HB. I had my first scan last week and my OB just saw nothing. And my 2nd appt is next week. I took almost 7 pregnancy test just to make sure that i am pregnant. I went on to laboratory and re check there if i am really pregnant and the findings are positive. I think I will be able to be okay if I got to see and hear my baby next week ;( advice please.
