Good Day! i just want to be clarified by this. i am using primolut n to postpone my period. The start of my period will be on Dec. 17 and accdg. to what i have read it should be taken 3days before cycle begin. I asked one OB Dr and she advised me to start 7days before. Could i get pregnant with unprotected intercourse even im using primolut n because i think my timing is not right. pls help me! thank u!
