How many weeks pregnant were you when you found out you were pregnant?

3 weeks when I started feeling aches in my belly and the most obvious one, my monthly friend didn't come to visit lol the drs probably thought I was crazy n just wishing I was pregnant because my first pregnancy test came back negative, but then I went back to the hospital because of the pains and aches and this time my pregnancy test came back PUHREGNAAANT 🤗
