Pregnancy?!?!

Me and my husband have been together for 4 years. 2 kids (once which was still born and a son who is almost 2) we have been trying for ovee a year to have another one. Wednesday 2/10/2021 I got a faint positive test after being 3 days late for my period. Thursday 2/11/2021 I started bleeding but stopped just a couple hours later. Took another one today 2/12/2021 and it was negative. Was this is false positive or a miscarriage??
