I'm so lost

Kimanii
Af was due the 31st... but I have no signs of it coming anytime soon. I usually feel like crap with a migraine, cramps, etc. but I fill completely fine minus a few light cramps on my left side. I'm now 2 days late and I'm only having clear discharge with a bad taste in my mouth.. could I be pregnant. 
P.s. My friend told me I was pregnant like a week or so ago and a few days ago I had a dream I was pregnant and didn't know and ended up with miscarriage
