Confused!!

Not sure if this is the place to post or ask this but, I had a miscarriage may 21st and been TTC since but within the last 2 weeks .. I've had a few headaches which I normally don't get headaches, I've had lower back pains like 3 times, I'm alwaysss tired but I'm also a sleepy girl lol .. seems like I pee alittle more than normal and sometimes I feel queasy but, I took a pregnancy test 10 days before missed period.. and I got negative. Could I be pregnant? Also I've had two dreams in the past two weeks I was pregnant. And seems like I have discharged more than usual. And just went to the bathroom and had light bleeding my period isn't due for another week.
