HELP !

Okay so i tested thursday and this popped up so i also started bleeding that Thursday as well. Can anyone tell

me what’s going on or have you experienced this? i tested again and took 3 non strip test and they were negative… i was think chemical pregnancy but i legit got off my period in the 1st and start bleeding on the 10th. i’m crampy but not period crampy. i made an appointment for the closest day but that isn’t until wednesday of next week… im just trying to figure out what the hell is going on… a week before i took the same strip and ovulation test and they were negative and thursday i definitely seen a line on the hcg test it’s very faint… HELPPP
