Can anyone please tell me. 😭

Before I say this I do want a kid but it's bugging me to find out so here are my symptoms... Okay I am12DPO I believe and my period should start tomorrow but I don't feel like it will and I kinda feel like I'm pregnant but I'm very gassy and been doing the number 2 like twice for 3 days and have like white kinda lotion discharge and I did have unprotected sex ( pull out method ) 2 weeks ago. The day my ovulation calendar told me I was ovulating. Could I be pregnant?
