Pregnant?

I had unprotected sex a few weeks ago and he wasn't sure if he pulled out in time or not 🙃 I have PCOS so getting pregnant won't be easy but we still try to be careful.. although I'd do anything to have a baby. I missed my period this month but I've missed many periods in the past when I wasn't diagnosed.  I've been Meds since Aug 2016 and have been regular since... any ideas? I'm going to wait another week before I test.
