hi there
Have been TTC for a couple of months and this is first month charting. My hormones are very random so its not easy to predict my cycle. So anyway...I have been using OPKs and also temp (trying to get the hang of the CM etc but not quite there yet) and for the last few days have been getting a faeint but getting darker line on the OPK. Didn't test yesterday due to work stuff and not getting home til really late and today when I tested there is no line at al. Not even a feint one. Is this normal, could I have missed the surge ion just one day????

Extra worried as DH has been away for work the last few days so no BD. If the surge was yesterday and we BD over the next few days is there still a chance of getting UTD? I just dont want to miss the opportunity and end up having to wait it out for another month!
