I'm sorry for the delay in response--was very ill for awhile
To answer your question--
yes, it can be quite normal to bleed heavily after taking prometrium
. Usually when women have irregular periods
, they tend to have a build up of material within the lining of the uterus. Prometrium causes all of that tissue to discharge and clots are common.
To prevent this from happening again, it can be a wise idea to keep the cycle regular. This can be done MOST easily with oral contraceptive pills.
