Did he pull out too late?

My husband and I use the withdrawal method. We are totally fine with getting pregnant if it does happen, and also fine if it doesn't. I kind of have a feeling that I'm  close to ovulating (based on time since period and I always get migraines right before, discharge consistency etc) and we had sex today but when I went to the bathroom after there was some seman-like stuff that came out after I peed (sorry tmi). He says he's pretty sure he pulled out before anything happened though. Maybe it was just discharge? That's never happened before though. Idk not even sure why I'm posting this... Just wondering you guys think I should take a pregnancy test this month or wait and see if I get my period. Opinions? Thanks 😊
