Hi I'm due to begin ivf on my next cycle but I'm worried because this cycle I started to use some progesterone cream thinking i wanted to boost any possible chance of a natural pregnancy as I has heard it could be beneficial. However I went along with the instructions on the tube which said to start using it from day 8. I now realise this is if it's being used as a form of HRT and not for TTC. I'm now in a panic because it seems to have done the complete opposite and I don't believe I've ovulated at all and am concerned that it will now through my cycle out for the forthcoming IVF which I have booked time out for. I can't speak with my clinic until Monday and dont k ow whether to stop using the cream as i think it might bring on a bleed which will be too soon I've not stopped using it because im not sure if it'll bring on a bleed which would be too soon. Any one used the cream before and can advise?
