Could I possibly be pregnant?

Hello, wait for a week or two. i started missing my period so about 4th missed period i took a hpt and it was negative. 4 more days still no period so i took another hpt and it was positive. and you can still have implantation bleeding? so dont give up, even if if you didnt get pregnant this month, there is always next month! i wish you the best and sorry to hear about your miscarrige.
