really need advice / help in general

i’ve been extremely stressed out lately. honestly more than usual with family and friend stuff. i don’t really wanna get into. but my period is now late by a week. i’ve been having on and off cramps, and constant mood swings, being gassy, white discharge, all that. every time me and my boyfriend have sex it’s protected. he never finishes in me. always out. even with a condom on. also we always do the “water check” and it’s never leaked. i’m probably overthinking all this but my period has never been late like this before even under stress. also i have a super religious mother who i absolutely cannot talk to about any of this and right now would have no access to really being able to test. i just really need advice and comfort right now. thank you girls <3
