Idk what to think...

So for the past few days my breasts have been so super sore and firm. My belly's been hurting and I've been cramping and my backs been hurting. People tell me it's just because I'm ovulating but I've never had symptoms like these during ovulation. I did how ever have them one before.I miss carried but didn't know I was pregnant. What do I think? Should I hold out the hope or just write it off?
