Missed period 3 months postpartum

Emily
I know that this is very common but I'm curious if anyone has had this experience. I'm more than 3 months pp, and I breastfeed. I had my period at 2 months pp right on time. I also had ovulation pain and spotting right on time after that period. My period is late this month. I feel pms like it might start but it hasn't. My husband and I have fooled around twice since giving birth and only once we had full intercourse. So while it's possible I'm pregnant it's not super likely. Is it normal to feel ovulation and still have no period ?
