according to my bbt im 5dpo i always got negatives on opk tests but i didnt do them at the same time everyday. My doctor has done a blood test to check if im ovulating but I wont find out the results of it until the day before af is due! Has anyone had mild cramps at 4-6 dpo and got a bfp? Ive never get af style cramps at this point in my cycle. Ive had a headache but i feel pooh at the moment woke up with the cold!
