Hi all, I've been TTC for 8 months. I have PCOS but regular periods, until this month... I started taking Tesco conception support vitamins about 3 weeks ago, not religiously so missed the odd day. I am now 3 days late for AF, had cramps for 5 days, and until yesterday I was a bit excited - then I googled conception vitamins and see that a lot of women's cycles get messed up by these tablets, with late AF, no ovulation etc. Does anybody have any experience of this? (I know my next step is to test but I hate doing this as I always get my hopes up and end up so upset. So I'm holding off as long as I can.) Normally I do get cramps a day or so before AF and it's usually accompanied by some dark spotting before normal flow starts (sorry!) but this month there's been nothing at all. As far as other symptoms go, I've had a few headaches (normal for me around AF), slightly sensitive nipples, maybe heavier feeling boobs but not bigger or painful, and a few nauseous/dizzy moments. But nothing really standing out to me. Wondering how optimistic I should be. Any help would be so appreciated.
