Hi it's been 8 month now we are trying to conceive but no luck I have regular cycle period. Apparently this month I feel a lot tired nausea backache and after my ovulation period at least after a week I didn't feel like having sex. My Af is due on 21. My basal temp vary from 96.5 to 97.8 at ovu and then 98 through out. Please help I got lower pelvic cramps too but this happens every month. Is there any fertility issue with me or infection
