On birth control but let my boyfriend finish inside.

I really need reassurance. I’ve been on Loestrin for about 6 months now. I’ve been taking it perfectly, at the same time every day. I was only about 3 hours late on taking it about 4 times but that was more in the beginning.

My boyfriend and I recently had sex 4 days after my period. I let him cum inside me twice but I am nervous about the odds getting pregnant. I spoke to a pharmacist if I should take plan B and he said I was fine and shouldn’t stress. However, I am still nervous. I am aware there is a 99.7% success rate with perfect use but there are still chances.

Now, Im 11 days away from my period and Ive been feeling nauseous and have an increase in discharge that’s creamy. What does this mean? Am I fine?
