Menstrual cramps for two weeks but no period?

Yikes :( Well, here it is. My period has never, ever been anything even close to regular. No real rhyme or reason I don’t think, I’m not a stressed out person in general or an extreme athlete and I’m very healthy aside from the fact that I do drink more than I should probably. Anyhow, I usually get my period on AVERAGE every ~30 days. So this current one would have been due anywhere from about October 25–30. I think. I can’t even remember when last months was, but I know in August it started about the 25th, probably similar for September.

Well, around probably the 25th of October I started getting cramps, the usual, sore boobs came a few days later, I was moody, blah blah. I expected it any day. It never came. But the cramps have continued on and off. Literally I have about three a day, sometimes none. Sometimes more. Sometimes I’m positive that my period just started, and I go to the bathroom and nothing.

So, it’s, realistically, at this point about a week late, having had cramps for two weeks now almost. I am sexually active and I did stop using birth control, but we use condoms. We are not 100% diligent though and there have been a few times we’ve done it for a minute without one on. SO?!??!?!?! Yes I’m going to take a pregnancy test in the next day or two, but I don’t want to do it until my boyfriend can be there and we have different work schedules so it’s tough.

Any insight onto this? If I have always had irregular periods should I even be as concerned as I am? For the time being though I’d love to hear your opinion on what could be happening, maybe for some peace of mind, or the opposite.

I have been particularly stressed with work the past ehhhh couple weeks to a month. Also, just a few months ago, I almost didn’t have a period, I spotted for like 2 days and that was it. Then it came normally the next month. Soo :( I guess it’s just the lingering cramps that are throwing me off…...
