Rosie your course sounds really interesting, of course we're all going to come to you for medication advice now 
I've not had an alternative to metformin suggested but I've read that if the gastro effects don't settle then switching to extended release can help.
Borris I'm so excited for you! I understand how totally nerve wracking it must be though. I hope you get more good news today!
Kellz as others have said, LP tends to stay the same length and it's the follicular phase that can vary. If you've ov'd late, you'll get AF late. Fx it stays away though!
Genghis Christmas can be a difficult one can't it? Hoping we'll all be pregnant by then!
Hopeful welcome! Symptom spotting can be very stressful but very hard not to do it. How long have you been TTC? I'd hold off another week before testing as 7dpo is too early to get a positive. Symptoms can vary between different women and you're always more aware of things when TTC so might not have noticed certain things before.
Fuzzy thanks! How are you getting on?
Sammy great news about the lining! Fx for Thursday, so exciting! Hope time passes quickly for you.
DizzyN fx it was ov but keep DTD anyway if you can! Just over a month until the SA then? Waiting for appointments always feels a bit frustrating. At least you'll be able to plan your next steps after that.
Bird I hope AF clears off soon so you can get back to it. Having chats like that can be difficult but I think it's important to do. Hope you both feel better for it.
DizzyM good luck with the OPKs, which ones do you use? I think I might take your advice and get a GP appointment booked in to discuss the side effects. I'll need to see them to get a repeat prescription anyway but I've been waiting for the gynaecology report to arrive, not here yet though!
Thanks for the birthday wishes everyone! I had a lovely day and managed to go out for lunch without needing to run to the loo which was good. The queasy feeling still comes and goes though. I managed to stick to my low GI diet apart from a very small slice of cake so quite pleased with that! I really need to start DTD in case I actually ov but have felt too bleugh to even attempt it!
