Changes in period on the pill

I am 44 and I experienced severe period pain and heavier bleeding after both COVID jabs. I had my booster in December, had one period since that repeated the pattern after the jab. I am on day 12 of my pill packet and have period pain and have started bleeding (normal period blood). This is very unusual for my cycle. I am hoping to put it down to the jabs but before Christmas I had a breast cancer scare which has left me with health anxiety. I am aware that I could be pre menopausal. I am guessing it's too soon to go to the Dr with just one occurrance?
