Need advice!!!

So I’m on the Ridevidon pill and I’m 15, my boyfriend and I had sex 4 days ago without extra protection.

Then I went out on New Year’s eve and forgot to take my pill so I took it around 2ish-am on New Year’s Day.

I’ve been doing other sexual things with my boyfriend today and yesterday but I always get stomach pains after he’s fingered me...

Anyways, I’ve been to the toilet and I have some pinkish, light discharge ( sorry ew )

I’ve had a miss-carriage before :/ and I really cannot get pregnant again. Please help me with advice and calm my nerves,

This isn’t a sign of pregnancy is it??????
