Lizzy wow, it’s all go! Keeping fx for you, exciting times 
Pulledapart welcome! Lots of great advice here - for PCOS the main advice my consultant gave was to eat Low GL to help regulate blood sugar, as PCOS is a metabolic disorder, so balancing insulin can be really helpful. I know you mentioned AF had just started: do you have regular periods and / or know if you are ovulating? For lots of us the biggest symptom of PCOS is irregular and anovulatory cycles - making TTC somewhat difficult if there’s no egg to fertilise. If you’re not having periods or are having periods but don’t think you’re ovulating, would def be worth seeing your GP…
Rufus thanks so much! Well my cheapy OPK went DEFINITELY positive by 5pm yesterday (Friday), with the test line by this point now darker than the control line. After the peak on the CBFM that morning, DH had already got his marching orders, and we DTD again this morning…I’d had another ‘peak’ reading on the CBFM, but I’ve read that it automatically gives you a 2nd day of ‘peak’ after the first, so not sure how much stock to put in that. Regardless, by 10am this morning I’d had a negative OPK strip, so between yesterday, today and tomorrow (Sunday), I’m hoping that we’ll have timed it right in case it isn’t a false positive. I’m annoyed with myself for being so relaxed about DTD last week - my CBFM was giving ‘low’ readings until it jumped straight to ‘Peak’ on Friday, and didn’t have any EWCM, so given my body wasn’t giving any indications of being remotely fertile, and it was so bloody hot, DTD wasn’t really a top priority. Hopefully the ‘targeted rifle’ approach rather than the ‘machine gun’ approach is ok as long as the timing was right. Not much I can do about it now!!
TMI, but does anyone here who is ‘O’-ing not get EWCM? I didn’t have any (though it had changed, apols for TMI, from sticky to creamy…so was going in the right direction, possibly watery today, but def no egg-white) - so even if we have timed it right to catch an egg (if there is one!), don’t know how much chance there is without ‘fertile’ CM. Was very very liberal with the Pre-Seed so hoping that might help to compensate….!
Oh and also TMI, does anyone else lie with their legs raised afterwards? I’m dubious whether it really makes any difference at all, but DH said even if most of it gets where it needs to be right away, giving gravity a bit of help surely can’t hurt? So had the deeply unsexy and completely hilarious moving me round by the ankles to get my legs up the wall with a pillow under my bum. We had to laugh!
