antibiotics and birth control help!

Hi ladies,

So i’m on the bc pill, and I take it the same time everyday (within an hour) that i’m supposed to. Yesterday, I had sex without a condom (but he pulled out.) The last few days i’ve had a scratchy throat and now swimmers ear. I was planning on going to the doctor today, but i’m worried the antibiotics would some how mess with my birth control and could cause me to become pregnant. Am I just overreacting??? please please please help! I could really use some advice.

Please stay kind!

Thank you in advance!!
