I have had 3 miscarriages and been prescribed Progesterone from day 21, but I am now late with BFN and I am sure it's just delayed my period. Has this happened to anyone else?
I would be showing positive now if preg as 16dpo, also no signs and opk's also completely clear (as I know they can also point to preg if they are super dark at missed period) so am 99.9% sure it's the effect of the progesterone.
In the majority of cases, you won't get your period until you stop the progesterone, which is why you have to do a pregnancy test
Your period comes due to falling levels of progesterone, however if you're taking progesterone, even if you're not pregnant your progesterone levels are artificially high, so will in most cases keep your period away
