Cramping!

Jennifer
Man this sucks! I have been having lower back aches for three days now and cramping. My period isn't for another 20 days! I'm pretty sure it's ovulation but I'm so uncomfortable. Been using preseed for the last few BD's. Wondering if that's it? Could it cause cramping? Boobs dont hurt at all just got some crazy lower body issues. Is anyone else experiencing stuff like this?
