advice? need someone to relate too?

is it normal that i get scared that my period isn’t gonna come. I’ve recently lost my V and started getting more sexually active, and were being safe (using condoms) but like i still get anxious if my period is gonna come. and the 1st time i wanted to cry bcs i could’ve sworn i was but then friends said that’s how a lot of people feel after. anyways if you do feel like that or use to can you give me some tips or advice how to stop being so anxious about it and thinking that way?
