TMI warning I have a question.

Me and my SO had sex then I jumped in the shower and I was rinsing off and had what looked like ewcm. He pulled out cause all though we are ttc I haven't had a positive opk yet so I don't want a uti. Anyways after I rinsed off I put my finger inside and it was just white creamy cm no ewcm inside. So am I close to ovulation or was it just my cum?
