I almost never get cramps aside from some mild cramping to let me know that she’s here and that’s it. I got the first dose of my vaccine close to two weeks ago and my period was late. I assumed that it was skipping like it sometimes does but nope, it came today after almost 2 months. I’ve never felt cramping like this before, I had to stop what I was doing and I’m going to try to take a nap now to see if it eases before my next class in a few hours. I feel so queasy too. Can I take a panadol/paracetamol to help with the pain? Has anyone else experienced changes with their period after the vaccine? I had Sinopharm (idk if I spelt it right)
