In fertile window and in pain

Lynzee • Mommy to Ammarie, born on March 3,2016!
Okay. So my period is confusing. Last month I had 2 periods, so I ovulated very quickly after them. The first started April 13 and ended the 22. second period ended May 5 (started April 29). 
I'm supposed to be ovulating tomorrow, I took an ovulation test today and it was negative but I'm having pain in my right side, probably where my ovaries are. Is this normal for ovulation? 
I'm also confused because since I had  two periods, in such s short amount of time, maybe I ovulated twice and could be pregnant? I've been dizzy the last three days, and a little sick to my stomach. 
Help? I'm really confused.
