Waiting on my period!

So I had sex September 30th and I am on the pill, on the 3rd of october I had my expected bleed which was rather light, only brown and then red blood when wiping? two weeks after I had a UTI and then I was experiencing swollen tender breasts, fatigue and backache, I took a test negative, 3 weeks later I have took a test again it is negative but I am experiencing extreme bloating, tiredness, sore boobs, backache & I have been noticing I have a heightened sense of smell and constant crave for sugar ???? but PMS is due in 5 days? I have been diagnosed aswell with BV and currently on antibiotics for the past 2 days will this interfere with my period and/or the pill?

Should I be worried about my last sexual encounter or is my body just fucked up and run down lol 😂 !!
