hi, My last periods was on Sept 09th. I havnt had another one since. I had pregnancy test done(both urine and blood ), both came out negative. Doc gave me primolut n . I took 2 tabs 3 times a day. Its been 4 days since I stopped it. No periods yet. How long after stopping primolut n should I get my periods. Are there cases where one does not get periods even after stopping? In that case what should one do?
