So period due 9/10/19 but got a bleed on 6/10/19 for 2 1/2 days was not a normal period for me

Took a test before bleed due to nausea faint positive

Took a test this morning a day after bleed stop and faint positive

I’m known to bleed in my pregnancies and loss of twin in last pregnancy 4years ago

Loss of twins dec 17 and jan 18

I think maybe a chemical but would they still show positive fr negative
