confusion

my bf & i have sex pretty regularly & he cums inside me every time. i’m not on bc & haven’t been since september. i took a test yesterday morning & the normal line showed up, then abt a minute later the second line shows faint but visible. a little after i took the test, i went to the bathroom & when i wiped there was a light pink discharge. later yesterday i started to have a light flow of blood, & cramps. today i’m still bleeding but not a lot at one time. i can use a light pad for abt 4 hours bc it’s not that much to have to change every hour. i regularly used tampons but because of the flow i’m not able to use one. i usually bleed heavy also. i was supposed to start my period today. which i still have a medium light flow. idk what’s wrong but please help. 😂 i’m super confused bc i’ve had this problem before but this time it’s different.
