So...after great advice on here I have ordered some OPK cheapy strip tests from eBay. My cycles have been irregular since my MMC in April & we have been ttc practically since then with no luck. Question is...when do I use them from? I've tried looking on line & it said if you get a line then dtd that day & the next day. Is that right? Spot the novice! Cycle varies between 29-35 days
They can be unhelpful with regards to irregular cycles because they can give misleading readings. If you do use these give yourself a set time limit re use eg no longer than 2 months and seek further medical advice after that time.
Can the GP arrange for you to have a blood test done to see if you are ovulating?.
Starting around day 10 sounds about right. A luteal phase (the between ov and your period) is 10-16 days for most women. So using your shortest cyle and the longest "normal" LP, that would have you ovulating around day 13. And most women get a positive OPK 24-48 hours before they ov, so this would be day 11/12 in this case. So starting on day 10 sounds reasonable.
