Need advice asap

Okay so I got a positive pregnancy test on Sunday 29th April. Today I’ve been bleeding. It’s a mixture of brown, red etc. Had a sanitary pad on and its very noticeable. Had mild cramps but not as bad as period cramps. Has this been a false positive and I wasn’t actually pregnant or is it normal? Had 2 miscarriages already this year so I’m hoping it’s not a 3rd.

EDIT - 4th May—turns out it was a miscarriage. Chemical pregnancy they called it. It’s the 3rd one this year. Absolutely devastated and disappointed in myself.
