I started Monofeme as soon as it was prescribed to me so I didn't start on it during my period.
I heard that it takes a combined pill to be fully effective after one to three months rather than the generalized rule of being protected after seven days. This is why I'm worried whether I will fall pregnant or not.
Also, before the 13th day of having unprotected sex, I took the pill consistently as instructed; have not missed a pill and took it around the same time everyday.
