Vitamin b complex and vitamin d are not going to interfere. It is what most fertility specialist tell you to take because they do help. I live in the US so I don't know where but I get mine online at swanson vitamins or amazon.
xxemmyxx, you may want to look into something like Vitex to help regulate your cycle. It's usually helpful for women who ovulate late, sometimes bringing ovulation up as much as 7-12 days. It also helps lengthen your luteal phase to give the egg more time to implant. I've been using it for 2 months and I'm really happy with it so far
Good luck to everyone still yet to test! I'm 8 DPO and trying my best not to obsess about every tiny little symptom. *cough* yeahright! *cough*
Xxemmyxx, I would recommend taking vitamin b complex and vitamin d before trying Vitex is great if it works but if it doesn't it than cause more damage than good. My specialist hates vitex because if it doesn't work it can set you back six months if it doesn't work. If you are just ovulating late but have a normal literal phase that isn't as much of a problem at having a luteal phase defect. I now ovulate normally around cd30 and have a 14 day luteal since my miscarriage that is my normal but even though I ovulate late I still have a normal literal phase. Before though my cycles were all over the place but just taking those vitamins regulated them. So vitex is great if it works but it is horrible on your body if it doesn't. Anyway i am not say don't try it or something like it. Because you can and it may work for you and be great. I was just giving you a heads up. My specialist said if he had a guarantee that it would work for every patient when would love it. Scooby,I am so glad it is working for you. I wish it did for me. Because the benefits would have been awesome. Because it sucks to have long cycles. I guess what I am saying is I wish I did more research first before trying so I knew all the pros and cons.
Thanks so much for your advice ladies. I have only just started using opks the last 2 cycles. I had a positive opk on cd26 last cycle and a positive on cd28 this cycle. Last cycle my luteal phase was 10 days which is on the short side. I was going to wait and see what it was this cycle. Where do you get vitex and vitamin b complex and vitamin d? I'm in the UK maybe I could get them from Hollands and barretts? I need to do some research around all of them. I am a bit scared to take stuff that might interfere. Is there a reason why people don't like long cycles (apart from the fact they are long and annoying) I mean does it hinder my chances ovulating late?
10dpo is what I hear to be about the best time to start poas. You can do it!! 3 more days and lots of baby dust to you!
I hope it gets darker in a couple of days! Other than the stomach bug weirdness, I haven't had any symptoms. I don't recall having symptoms with my other 2 either. 
Lots of baby dust to all of you!!
