Help.. 😩

I had a miscarriage Jan 8th 2016. Around Feb 20th I got my period. It lasted until around the 25th. After I had my period I was sill having sore boobs and back aches. Increased appetite. So I took a hpt and they both came back like this? Is this my rainbow baby?! According to glow I'm very early in my pregnancy. Would I have convenienced before my period?
