my period on birth control

Hi guys!

So, I was supposed to get my period last thursday and ever since last thursday, I have had small brown stuff when I wipe. it’s not discharge though. additionally on thursday i did have a little bit of pink discharge and i had a tiny bit of blood the next day, but it stopped very quickly. is this my period? the brown stuff lasted for about 5 days which is my typical time to have my period. i’m just confused because i didn’t need to use tampons or pads because there was basically literally nothing down there but i did have the worst cramps. after about 5 days it’s all over. i’m just confused because last month it wasn’t like this at all, but that’s probably because i have been on the pill longer now. help?? was that my period or is my period just really late because i barely had actual blood
