CAN SOMEONE HELP ME ASAP!!

i started my bc pill dec 15th for the first time. last time i had sex it’s was unsafe on dec 30th. the next day i started my inactive pills and got my cycle within 24 hours (full flow). fast forward to january, almost all throughout that month it was nothing but spotting literally almost the whole month. my “cycle” for january was spotting lasted for 3 or 4 days, instead of my normal flow. now in february i’m not experiencing any spotting. just thick white discharge and sore boobs that feels like they’re heavy/growing but the fitting of my bras feel the same as before all of this. is it normal to have spotting instead a actual flow during inactive week?? or should i be worried?? bc i’ve stressed out over this for the longestttttt!
