Could I be Pregnant???

My ex and I had sex almost everyday when we lived together. This was Late March, Early April. My last period was weird. It was light for 2 days, heavy for two days, then stopped. Here lately I've been having symptoms. Like white discharge, dizziness, fatigue, nausea, been tired more than usual, breast enlargement, etc. I took a cheap pee test and it came out negative. But i think its more than that. i have a gut feeling i AM pregnant. Need help.! thanks. (:
