First period after second shot was way different 32F

I got my second Pfizer shot on June 3rd, and got the typical chills 12 hours later and slept a bunch and I was fine after. I got my first period after receiving the shot on Friday the 25th. I track my periods every month, this one was right on time. However it started ABRUPTLY like full force and the heaviest period I’ve had since having kids. It was also the most painful I think I’ve ever felt. The cramps were out of this world. Ibuprofen helped and I sucked it up and thought ok it’s just a heavy one this month. Then, today (Monday) I wake up and it’s gone. Just completely gone. Normally my periods start gradual and end gradual. One day of light, 2-3 days or normal/heavy and one day of light. It was just two days, mad blood, awful awful cramps, then ok cya. I don’t think I had a miscarriage because my period was on time, and I didn’t see any tissue or clots. Idk I’m just concerned I’m going to make an OB appointment but I was wondering if anyone else had anything like this?

Not an anti-vaxxer.

Update: period came back and I’m still bleeding full force. This is crazy. Trying to make an appt with doctor but having issues, my ob is all booked up til November so I’m trying to tell them this is urgent but apparently it’s not.
