Ok. My story is... always very punctual 26 day visits from af. Day i was due had constipation, pain in right ovary area. Day 2 after af due had pre-af cramps. Over next couple days had random leg cramp and back pain. Went doctors four days after af was due, given fibregel for constipation, temp, blood pressure, urine infection, kidney function, diabetes; all fine/normal. Now day 7 no af all bfn even with fmu. Back pain reduced, no cramps since day 2, no spotting, no vomitting, constipation clearing. No other pg signs. Since woke up today pain in right side is very bad- worst its been. Made out of hours gp appt for 5 hours time. Anyone had similar? What could it be?
