Af is due 10/7. Husband and I had sex the week of ovulation 9/21-9/27 (positive ovu test 9/23-9/25. Yesterday had bad headache all day and my left side ribs started hurting around 4 and by 6 the pain moved around to my back ribs/shoulder blade area for the rest of the night. Today I've been smelling food that isn't there. And my right side ribs just started hurting. Normally I only get this kind of rib pain if I'm doing dishes forever. Could this be really early signs? Could I be farther than I think? Last af was 9/8.
