Hi Ladies, after some help. Since yesterday afternoon, I have been suffering with Period type pains, currently on CD 22, usually AF has arrived between CD34-38, I'm currently on Clomid and Metformin for PCOS. I have back ache also and tender breasts, and generally feel washed out. Had alot of wine to drink last night, but I already had these symptoms yesterday afternoon. Its almost like trapped wind, but its not, everything is working (bowels etc, I know its lunchtime and too much info), has anyone ever suffered like this, could I be ovulating!!!!!!
