I'm so confused..could I have Endo?

Stella • lost baby #1 at 15 weeks May 2017. Pregnant with our rainbow baby!!😆💓due Sept. 2018

ok.. I'm supposed to be ovulating next week, which is all well and good. but my boobs are sore and I'm feeling so crampy like AF wants to show up. and whenever I have a full days work my pelvic area hurts and is sore all over from all the lifting and walking I do.. (baker and cook) I'm not overweight at all.. 5'7 and 117 lbs. I'm just wondering if this could be endo? anyone have any experience with this?
