Lower back pain and missed period
I am 29 and I have endometriosis. My husband and I have been sent to see a fertility doctor in the next few weeks by our obgyn after not being able to get pregnant. Since I have been off birth control I have had very regular periods. Currently I'm 8 days late though with very bad lower back pain and some lower pelvis cramping. I've had cysts on both ovaries before but this pain feels different. It's uncomfortable and irritating but not sharp. I did take a pregnancy test just to rule that out and it was negative. Any suggests on what it could be? We have to pay out of pocket for the fertility doctor so I'm wanting this to be resolved before we go. Thanks.
