Could I be pregnant?

My most fertil day was on the 19. I was supposed to get my period today but instead I got a stretchy white cervical mucus , and alot of it. I've been crying over everything. If my husband says I look alittle bloated I start crying. If I see a commercial about baby's and start crying and feeling so emotional. I can eat alot and not get full, the food has a certain taste to me, seem's more tasty. I pee alot, like 3 time's in one hour. I sleep alot, my husband asks me " how do I do it" I seem to not even wake up, I can sleep for hours, even when im watching t.v. I just fall asleep, well I fall asleep every where :-P even when me and my husband are cuddling I fall asleep on his chest all night long until I have to go pee :-P I look at food commercial and my mouth starts to water, my bbt is still high since I been checking it since my ovulation has stopped, my bbt is really high in between from 98.6-99.5 so high doesn't go low. Im one day late on my period and like I said I only noticed alot of cervical mucus, hoping it's the plug pregnant women get :-P this is my first time experiencing alot of mucus instead of my period. ..I've been trying for 4 months to get pregnant and im hoping this is my month :-D
