My periods have been irregular the past couple of months and I had been ttc 2 years, now ending my toxic relationship and moving on I may be pregnant?

I began having cramping on and off, after that stopped the terrible headaches came. So bad it hurt to move my eyes. Then it was followed by breast pain. To top it all of my wisdom tooth began to flare up and my mouth is in so much pain. Maybe it’s a really bad pms symptoms? Idk I need any advice does this sound familiar?
