Baby #2 Update

Went to the clinic today to find out how far along I am because they keep going off my last period and I was on BC(Birth Control) when I had my last period and got off after so the clinician did a ultrasound and we couldn't see anything because I just got a positive test June 23rd 2017 so she's saying that its definitely to early to see baby and I'm only about 2-3weeks possibly. I don't have my 1st prenatal check up July 31st 2017 so thank God its far out. I can't wait to see our lil baby on the screen.
