Help!!!

Me and my hubby are trying to conceive and I've been tracking my ovulation everyday. Well for the past week and a half I had high fertility and ewcm. So we baby danced through this whole time. Well starting Monday I had weird symptoms. Pain on my left side,lower back pain, headaches, extremely tired, sore breasts,and moddy. Well I took an ovulation test this morning and its back down to low fertility. I have not had a peak. And I'm still feeling the symptoms. I don't know what's wrong! Please help I need advice??
