Pregnant ?

Hello! I’m on the combination pill and take it at the same time everyday. I’ve also been on it for awhile. I am very sexually active and my boyfriend pulls out everytime. There was one time this month he pulled out cause he thought he was going to finish and did a little and then put it back in and kept going. There was also another time this month where he pulled out but his cum was dripping down into my area. My breast have been getting a little bigger and kinda tender not awful and I’ve been nauseous and tired. I’ve also been a little crampy here and there. I’m suppose to start my period in 6 days but IM SUPER FREAKING ANXIOUS. What do you guys think?
