I got my period!!

Last time I had sex was January and I had gotten my period before having sex. (The sex was protected). I then got my period in February but decided to take a test to be extra sure I was okay (idk I’m just like that??). My test came back negative and I already got my period this month (March). I’ve had my period for both months after so I CANT be Prego right?? I also got a negative test AND it was protected sex! I’m so paranoid! but I just wanted to put this and get it out there because I’m a big mess lol. I still get so worried after having sex and I literally can’t anymore lol. But yeah I’m so mentally unstable I literally need constant reassurance that I’m okay :(. I’m just such a scaredy cat — but yeah help me keep my sanity and reassure me babes? I’d really appreciate it
