Advice ?

I have been on birth control for like 5 years (the pill) and have been with my boyfriend for 4 years. We don’t use condoms but he always pulls out WAYYY before hand and I have never had an issue and t take my birth control regularly and have had regular/exact periods every month. This month has been my first month at college and it has probably been the most stressful of my life. Had my first panic attack a couple weeks ago and thought I was dying ever since then I have been having chronic anxiety everyday but besides that. it’s a Thursday as I am writing this and I usually start my period on a Wednesday( every month) . I feel like I am getting the symptoms of my period .. like cramps, breakouts, mood swings, discharge ect.. but no bleeding yet. I am just scared and some reassurance or advice would be really helpful.
