I think I’ve had another chemical 😭

I had a positive test yesterday morning only faint but noticeable well literally 10 minutes after seeing the line I started to bleed lightly brown/pink and had slight cramps on lower tummy and back more of an uncomfortable feeling than pain It was my 7th day late for my period yesterday usually when my period is coming on I have groin aches aswell as the normal period aches but I’ve had nothing there’s not been that much blood but I did have a stringy tissue like blood thing come out.. If this is a chemical this would be my 10th one in a row I don’t know what to do!
