Hormones, ovulating or pregnant?!!

I'll start by letting you all know I'm extremely inpatient!

So.. I've been on the depo most of my sexual life. I got pregnant on the pill with my first (I missed ONE day!) Then with our second, I came off the depo. They told me it could take 6 months to 2 years for my body to return to normal but life had other plans and we conceived our second within 2 weeks. Now I'm back off the depo and was only on the pill for a month before coming off it to try for baby number 3.

It's only been 2 weeks since coming off the pill and sorry if TMI but here's a list of my symptoms:

Cravings for specific foods
Adversions to some foods
Nausea
Increased libido
Minor cramping
Tender breasts and nipples
Darker and larger areolas
High, soft cervix
Increased discharge (watery)

I cannot work out for the life of me if I'm in really early pregnancy, ovulating or if its simply just hormones while my body readjusts! It's too early to take a pregnancy test and OPK is only a faint line. Thoughts??
