No suggestions as you sound like you have it under control :) plus I'm not up on the latest blue sway wise. But it sounds like you've been doing the HE diet for a good time now. Did you run your sway past atomic? If not I'd suggest starting a thread under the the ttc a boy subforum and just mention everything you've done/are doing, then you can get feedback from the lady that created this whole swaying business here. Also other blue swayers may offer some input as well, there's alot of blue swayers atm, more than I've seen in any case!
So you should be due for a flashing smiley at least in the next day or so, this will make you our first April tester I think [emoji3]! Let's hope you start the bfp ball rolling for us all!! And also not silly at all to not know when you ovulate. I've been trying so long now I feel like I know my body inside out [emoji23][emoji23] but in saying that I still temp to confirm as opks, pains, cm and cp are only a guide, often a very helpful guide but sometimes a confusing one lol.
