I have been taking Provera 10mg for 25 May, i.e. from the first day of menstruation continuously. The drug was prescribed due to an abnormal result of hysteroscopy - the therapy is expected to last 6 months. Since taking the drug, I had a slight spotting in the middle of the cycle. The next menstruation was very scanty and lasted 4 days. Yesterday I had a gynaecological check-up - the doctor said that there was no ovulation at all, he did not find a possible pregnancy. I, on the other hand, suffer from pulling lower abdominal pains all the time, quarrels in the ovaries, and I'm in 17dc. The doctor said that this was a side effect of the drug. Is it possible or can the doctor be wrong and not notice ovulation.. Pregnancy test 13 days after intercourse negative. The doctor said that I may not have both ovulation and menstruation with this drug. I don't know now to what extent the pain I feel is the result of anxiety and how much is the result of an actual ailment, and whether it can actually be caused by the drug. I will add that the last cycle lasted 23 days, so theoretically I am a week before my period. I'm 42 years old.
