The women will be randomly allocated into Menohelp Barij® or placebo groups. Sequentially numbered packages containing Menohelp Barij® or placebo will be used to conceal the allocation. The capsules, identical in appearance, will be identically packed, and given to participants in order of their inclusion into the study.

The investigator involved in participant recruitment, data collectors and the participant will be blinded until end of study.
