So hubby and I did the deed Wed and Sat I ovulated Thur Fri. From Thur to Mon I felt slight nausea which I was putting down maybe heat and hunger as it was mid 30s deg and was usually only morning and evenings/night. So implantation could be anywhere starting tues or fri. And today. Thurs. I felt little bits of pain in my belly and lower back like a lighy stitch but didnt do any major exercise. AF is due wed and only stopped taking contraception few days after new year so anyway to know before AF if its all in my head or not? I am over analysing everything!
