Ttc second at the mo. Irregular and quite lengthy cycles of 35-43 days. Fairly sure I OVd on day 18, DTD regularly around this time. Have had a blazing positive dark line on my Ovaviews for about three days, on CD 37. Terrified to get a HPT as the disappointment is crushing. Going to maybe do one Thursday. Just wondering if folk think this is a promising sign- would u expect the Lh surge that comes before AF to lead to such a dark line, for so long? No symptoms other than a little pulling around the uterus area, felt periody about two days ago but no sore boobs or nausea or anything. Thanks...
