Hi...my cycle is around 36 days & I have been using an online app,diary & obvious OV pains to determind when in the month is the best time to dtd. However...I haven't checked diary & my online app had predicted OV for a 28 day cycle! I had OV pains Monday-Friday last week & dtd Thursday. If my cycle is 36 days & the pains were OV pains...does Thursday count this month? Worried I have missed our chanc this month thanks to me relying on an app to do my thinking for me!
