Cramping 4 Days after period?

my last period was April 1-5. my cycles are 28 days long and this last period was normal for me. Im TTC but never have i've had cramping so soon after a period. The cramping is mild and in my pelvic area, I've also felt some shooting pains and twinges in my belly. I've had all week since my period ended and I've noticed some watery discharge. Isn't it too soon for ovulation? I'm really confused, what do you think?
