I have been taking Boots branded conception multivitamins this cycle and I'm on CD20 with my CBFM still saying high. Not only have they delayed my ovulation but also giving me nose bleeds. I usually would have ovulated 5-7 days ago. Is this normal when you start taking these vitamins? Should I give it more time? I'm quite an impatient person and thinking I'm just going to ditch the vitamins and take plain folic acid tablets as I'm desperate to get pregnant.
