Cramps then no period

So, the other day felt like the day before my period. I had slight cramps, wanted all of the food and felt a bit short tempered. Glow was predicting my period to start the next day as well so all normal and on schedule.. So then I went to bed. What would usually happen when I wake up on period day is I wake up fine, go eat quickly then within 10mins my proper stomach cramps kick in (which are pretty bad) and my period starts.

Only this month, I woke up on period day totally fine. No cramps, no period. This was 3 days ago. What the hell.

If I am pregnant then its pretty much a virgin Mary situation as my partner has had early shifts and is asleep by 7pm lol and you're lucky if we've had sex twice a month for the last 2 months and are using condoms.

So this makes me wonder "wtf".

Has anyone else had anything similar to this?

I'm 26, pretty healthy, normally have a regular period. I've once missed a period due to stress but that took my dad figures death, my partners dad being put in a coma and my partner losing his job within 1 week for that to happen and life is pretty easy going right now. Would rather ask here than Google is as Google will no doubt tell me death is imminent 😂
