Hi ladies need a little bit of help

I miscarried last month at 6 weeks. According to glow i was supposed to get my period today however my partner and i have been having unprotected sex every other day. Sore/enlarged but bearable chest the last 48hrs.. could i be pregnant? Took a test and it was negative (i want to say faint positive) but i had 3 MCs last year and don’t want to get my hopes up 😢
