Irregular periods after plan b/std preventatives?

TW****

My periods have been EXTREMELY regular since I first got it at 11. Im now 24 with a 4 year old and 16month old. I knew the day my period was due with both my pregnancies because it was always on time. I got my period back at 3 months after both my pregnancies. Since I was assaulted (sept so 4 months ago) and had the plan B and STD preventatives they gave me (I’d have to look in my records what exactly was given) ive had extremely weird periods and irregular also. Usually 5+ days early or late. I feel like I have a hormone imbalance, dealing with INTENSE ovulation pain (worse than PMS) extreme pain in my ovaries, backache, headache, bloating, etc. also dealing with horrid acne that is the worst I’ve ever had and on top of that eczema when I’ve never had that in my life either. When my periods do come they’ve been one seemed like I might have been ovulating during it, cervical mucus like crazy, watery discharge with period blood. Others have had a lot of clots. Could I have a long term hormone imbalance from what had happened? Does it sound like a hormone imbalance to others who may have dealt with it?
