Pregnant?.. Or am I crazy?

I've been feeling a little off these past few days... Randomly feeling nauseous, out of no where food craving and sore nipps... Period is due in 2 days.. I ran out of pregnancy tests but had plenty of ovulation tests... Decided what the heck let me pee on one.. Weird?.. It came out positive...(this was yesterday) so this morning I wake up feeling queasy so I used another ovulation strip.. Yup u guessed it positive again. Sooo to my curiosity I buy a pregnancy test.. Can this be real?? Hubby and I have been together for 13 yrs zero pregnancies. I have PCOS and have been on metformim and clomid for the past 6 months.
