BFN...but symptoms

For the past couple of weeks my sex drive has been through the roof, my boobs are sore, I've gained 5 lbs and I seriously feel like someone has punched me in the stomach bc I feel sick all the time...and i feel drained. I just took a test and got negative. I had a miscarriage in february and these are the same symptoms I had when I found out I was pregnant then. Guess I will test again in a few days...it sucks not knowing :'(
