Period out of whack?

So i got my period March 16 for a few days. Then I Got it again March 27th for another few days. Then today I got my period or some spotting April 6.

I’m on low dose estrogen birth control, but I haven’t taken it since yesterday bc I lost my pack so I’m starting over this Sunday with a new pack.

Is this normal? Ivenever gotten my period twice in a month and so soon after the following month. I hope this isn’t a sign of ovarian cancer and can’t go see my pcp because I don’t have health insurance.

I’ve also been really stressed so maybe this is a factor as well?
