Sex for the first time??

So i had sex for the first time on saturday last week. We didn't use a condom But i am on the pill so that shouldn't be a big problem. I have been Told that it would hurt at the beginning and it did. I have also been Told that it was completly normal to bleed after the first time, But my question is...How long is it normal to bleed? I have been bleeding for four days now, But i only motivert When i am at the toilet and i haven't been spotting that much...? Anyone who wants to Share some knowledge with a Poor girl...?😅😅
