Harlee • Hey guys ! My name is Harlee , I am 19 years old, my fiancé and I have been trying to have a baby for roughly a year now but sadly we`ve had 2 miscarriages and have not been able to get pregnant ):
So I need advice, my last period was may 21st, i spotted June 18th-22nd, when AF didn't show i took a test and it was negative, what do I do? Could I be pregnant?
