Really Late Period

Aly

My last period was on the 7th-14th of December. I haven’t had a period since, today is the 25th of January.. Normally my periods come every 3 weeks and a half... it’s been 6 weeks since my last period. I’m not too bothered about missing periods but I’m having extreme side effects. I am so bloated at the moment, I have never been this bloated before. im extremely emotional at the moment too (which usually happens before my period) and i’m eating a lot (also happens before my periods) I have also broken out and I’m getting really bad cramps now.. for example like I woke up in the middle of the night due to a terrible cramp which went on for ages.. but there’s still no sign of bleeding.. i also haven’t been sexually active since my last period so i can’t be pregnant. i do have pcos but i’ve never experienced this before. what could this be and what do you suggest doing ?? i’ve been like this for the past week or so now.
