So last month I just started a new pill cuz my previous one was causing breakthrough bleeding. So I didn’t have sex the entire month until the day right before my period. Yes we used condoms and he even pulled out. Then the next day I got my period and it lasted a full 5 days. I’m on my second pack of pills and my boobs are sore. There is no chance of pregnancy right? Is this just cuz my body is still adjusting to the new pill?
