still no period?!

So I started the pill about 4 months ago.
I took it on time everyday
I had sex with my (now) ex-boyfriend about January 7 or 8th.
We used a condom thte first time, then unprotected the second time, but he didn't come in me.
I wasn't ovulating and it wasn't during my fertile window. AND I was still taking my pill.
I stopped taking the pill January 21st. (Mom lost her job so we lost insurance and I can't go to the doctor to get it refilled)
I haven't had a period at all since I started my pill 4 months ago. (Same thing happened when I was on the Depo Shot a year ago, I didn't have a period)
I'm dealing with a UTI right now, slight cramping, peeing a lot, a little burning sensation.
Anyways, my point to this post is, do any of y'all have a clue as to why I haven't had a period yet even though I've been off the pill for a couple of weeks? TIA💓
