Scared as fuck🤦🏽‍♀️

Okay so ive had sex 5 times in march without a condom. Never gotten pregnant on the pill take it at the same time every single day. Now i am given amoxicillin for a throat infection and i understand the interface and have not had sex since i began taking the amoxicillin. My period is due today and ive had slight cramps but no spotting nor one drop of blood. Sometimes i drink ginger to bring on my period but ive drunk two cups and still nothing but im literally freaking the hell out and need advice please and no judgement
