Ttc, COVID shot, missed period

Hi Ladies! I'm wondering if anyone else has had this experience and has any comments or advice..

I'm ttc for #2, I was supposed to get my period 3 days ago and I've missed it( I took 2 pregnancy tests, both negative) I got myCOVID shot 3 days before I was supposed to get my period and I've heard from soooo many people that their cycles were messed up after the shot. I've had cramping and white discharge but no spotting or anything.

Has anyone had this experience and ended up getting pregnant after? Did you get your cycle back? If so, how long did it take? I appreciate any advice!
