Am I safe?

So I had sex for the first time last night( I’m 20) and I’ve been on the pill since the 13th of this month and I’ve been taking them at the same time everyday. We used a condom the first time but since I didn’t like how it felt, we didn’t use it on the 2nd round. He didn’t cum inside me any of the times. My period is due in 6 days. I’ve been getting cramps and sore breasts but I’m not sure if they’re from the sex or my period is coming. My question is ... am I okay? Chances of pregnancy
