Pain in ovaries, sore , etc..?

Ok so I had protected on the third of July, a day before my period.. My period started July 4th. According to my period tracker iPhone app, I was ovulating on the 18th which is when we had again. Protected. I'm not saying I'm pregnant but I don't know if that information is important. Anywho, I had lower back pains, and my left ovary was hurting and now I feel it on the right ovary. My are sore. I also feel like I have pressure on my lower abdomen. Yesterday I felt kind of woozy. Like I would look at the computer or the floor and it felt like it was spinning a little bit LOL I'm just wondering if these things are normal during ovulation.. Maybe I hadn't noticed before because I never knew when I was ovulating and now that I have the app I do know. I'm basically have pms symptoms but I just had my period on the fourth and should not be expecting it until August.. so what's going on? I think I have ovary cysts because when I went for a check up around two years ago, the doctor said he felt my left ovary strange or something, and sent me to get it checked but my mother never took me. I'm 18 years old now, dependent of myself and haven't been to the doctor since so I am trying to figure out if it's important to get this checked. I am trying to get insurance as well.. My mom says the ovary cysts isn't a big deal but she's talks about crap she doesn't know.
