Questions!!

Hello! Sorry some of this might be TMI! But I just wanted some advice! So my boyfriend and I were sexually active 11/25 and he finished inside me... then we had sex again Black Friday weekend, and he claims he didn’t finish inside me. According to another tracking app I was ovulating that whole time we were sexually active, we haven’t had sex since that weekend due to his medication making him lose interest. BUT 12/09-12/11 i had old blood looking discharge, only when I wiped and barely on any tampons. Then yesterday and this morning (it’s still early) i have had discharge that was clearly mucusy like uncooked egg whites. I have had cramping that I thought was maybe my IBS. Honestly I have taken two digital tests and they have said no. I don’t want to call my dr if i am just freaking myself out making my period get all out of wack. I was on the pill but stopped taking it the week of 11/25. THANK YOU FOR ANY ADVICE YOU GUYS GIVE ME!
