IM SO ANXIOUS

I had sex over 2 weeks ago. We used a condom the whole time, he pulled out way before being close to finishing and I’m on the pill. I had sex again over a week ago week ago with a condom, he pulled out long before being close to finishing but this time I was on an antibiotic for my sinus infection (still taking my pill at the same time every day tho). I am anxious that I won’t get my period that’s due in 3 days just cuz I tend to overthink a lot but he didn’t finish in me at all and never put his dick in me without a condom. I’ve been having thick discharge and sometimes it is tinted yellow. Am I safe? I need some reassurance that my period will come in 3 days and I’m not pregnant.
