Hi,i took primolut n I there was blood withdrawal last month after 4 days completion.Now the next month,i didn't see normal period and Doctor asked me to repeat but 2 pills 3 times a day to meet up 30 days pills since my husband will not be with me cos he is going back and I want to fall pregnant.The doctor said I will see my period after 4 or 5 days of completion Today is the 6 th day but I haven't seen it yet.Is it compulsory that after taking the pills, blood withdrawal must come or sometimes it doesn't come.Im very worried
