I think you should contiue to test the strips because you are still early. I have the same 30/31 cycle and my cycle came on Feb.14. I was suppose to be fertile the 1st thru 7th. I started testing on March 1st and got the control line and a very faint test line.. I contiued on to thursay and got a darker test line but not as dark as the control line. So last night I decided to test again and both line was the same which mean I am about to ovulate.. So contiue testing and your result should become postive within the day or to.
hi,
thanks for responding, i have indeed continued testing, yesterday there was a line there but only ever so slightly again, had to tilt the strip a certain way to even see it! today there is no line at all. i will continue with the remaining tests i have left and see what happens, think i have enough to last me 6 more days and cover me until af. i am expecting af 18/19 March, so will see what happens.
