Littlebirdie- not constipation but I tend to get a dicky tummy around ov. Question.. Just summing up, I bd the day that I got a line turning darker line and then late morning the next day I got my positive result. Didn't bd that day as we were out the whole day and too hot. Following day, today, we managed to get a bd in the morning but when I tested with my strip only had a faint line. So in 24 hrs I've gone from a strong darker than control line to faint. The pee i used was very weak, almost transculent so not ideal. So is this normal? It was 24hrs from getting stronger to a positive line so could I have just got the positive result earlier if I had tested rather than going from a positive to negative in 24 hrs?
