Having pains around ovulation?

Ive been using OPK's and have had 2 almost positive tests since yesterday..My bf and I BD last night, Today I am experiencing mild cramp like pains in my lower right side. Does this mean that I am ovulating today? or that i am about to ovulate? also i've been breaking out more than usual.. Im really confused on all this ovulation sutff since this if my first time TTC. If we BD tonight do I still have a chance on getting pregnant this month? Im really hoping we didnt miss it. Thanks for the help. Babydust to u all :)
