Cyst questions PLZ HELP

Brittany
I've been ttc this month for baby #2 but my stomach started to swell up like a balloon, I have been experiencing weight gain these past 6 months and I didn't know why but my stomach never felt like this over the six months I've gained over 20 pounds, anyway I went to the Er a few days ago with pains they did a CT scan a found a simple cyst in my ovaries. Could this be causing my weight gain and could I still get pregnant this month?
