Ttc. Any thoughts?

My period was due on the 24th month and the past 2 months it has been right on time. But this month i havent gotten it.  My period last about 4 days and its already almost the end of the month. Is it possible to still get it? Or chance of pregnancy? I thought i was just having my regular Pms but now im rethinking     Ive been eating nonstop, extremely mood anything and irritate me even my fiancé breathing in my ear. Lol and i had some minot yet strong right side cramps. With white stretchy discharge kind of like ovulation discharge but of course its not that.
