Firstly thank you for reading. Im ttc my 3rd child with my DH. I have used opks this month, not much use, think i missed it, but did have O symptoms. We have used pre seed and BD every other day. I did a FRER on friday which was Neg. i have had sore breasts, feel sick, tired, really thirsty, stuffy nose, cramps and head aches for 8 days now. I usually have a 30-31 day cycle. My last period was on the 8th of Feb. Glow says im not due on til 14...WHY? Sister in law says its cos Feb is a short month. But ive still counted on my calender and im over my normal days....
