I take medication to delay my period, but it came anyway, but in a strange way
I'm 18 years old and it's not my first time taking pills to delay my period (i did it few times since last june) and right now I'm taking them for like 12 days and I woke up this morning to see some light spotting. Overall I was feeling bad, just like when my period is kicking in (bad cramps, dizziness, nausea, and I suspect endometriosis with this symptoms, but I haven't gone for any diagnosis yet). I go back to sleep and now woke up to see that there are no spotting, no blood and overall I'm feeling like normal. And I don't know if that's normal, or should I be worried? I read somewhere that this can happen if I'm not taking the pill on regular hours, but I was doing that, so yeah, I kinda need advice, because I'm stressed af as I have a important event in a few days. The pills name is duphaston, if that's important too.
