5 DAYS OF A POS OPK HELP???????

Hi ladies i have a question, i just got off the pill in May and got preg right away and had a Chemical preg, which is a early MC. And i still have not gotten a period, but i know i was not preg, cause i took a few test and then i wanted to track when i ovulated, so Tue Morning early it came back positive and that same hour i felt twinges and little pulling pain in my ovaries, but i thought those test only tell you a day before you are going to O. The two lines were the same color at that point but everyone says it is a pos. So then i took it again to confirm and again same thing, but alittle more obvious, next day i took it again and it was a little darker in the test line, that was wed, then thu and fri it was really dark in the test line, and now today sat it was darker then the test line but both lines were alittle lighter then all the other tests. Im still feeling those pinching feelings in my ovaries since tue, what the hell is going on , i thought you only ovulate for like two days, and it has been 5, weird. Can you ovulate longer when getting off the pill. Any advice???
