No AF. HELP! πŸ˜”πŸ˜”πŸ˜”

Myra

So I had my last af June 23 haven't had one since then. I took multiple pregnancy tests and one came back positive but all the rest after that One were negative.

Had my daughter in feb 2014 and I was one the depo shot for 1 year got off and just used condoms my husband and I decided to start trying since July 1st 2017 but I don't know what to do. Should I see a doctor or just wait longer for my af? I've had cramping and pelvic pain for 3 weeks! πŸ˜”πŸ˜”πŸ˜”πŸ˜”πŸ˜”
