Need your input girls! Thank u❤️

So I had sex on February 23. I’m on Birth control but had just recently switched the type of birth control I was taking, so we used a condom. I’m almost 100% sure it didn’t break because when he took the condom off after it was full of cum. I had my period about 2 weeks ago now. I’m a super anxious person that stresses out pretty easily. I feel like I look more bloated and feel kind of tired. My next period is in a little less than 3 weeks. I took a pregnancy test on Friday of last week and it was negative. What do you guys think?
