help!!!

So I gave my boyfriend head about an hour and a half ago. We just had sex but he did not cum and wasn't close. He just made about 7 strokes😂. I'm on birth control also and am on my 3rd pack, 2nd week. Last night I took my pill about 20 min late but other than that have taken it pretty consistently and just took my next pill for today. I just now went to the bathroom and wiped and had a little bit of reddish pink on the toilet paper. Should I be fine or?Â
