Last month cycle was 39 days don't know when I ovulated as surge wasn't picked up but had EWCM, attempting charting temps this month but they were all over the place like a rollercoaster on graph so I sacked that off and just been using OPK's from day 11, now on day 15. The last 4 consist of 2 from today and 2 from yesterday (the bigger ones are boots own brand). First one today picked but barely no line at all, thought that was weird so I managed to wee a bit more using the boots OPK and line is quite strong. What is going on! How can the one stop pick up nothing but the boots the line is clearly there done at pretty much the same time. I know it's still negative but possibly slightly darker than yesterday's. I don't think I'm close to ovulating as I haven't had any EWCM yet. Any advice? Feel like I'm losing my mind it's all I can think about.
