Hindi ako personally nag-try ng Pregina, pero a few of my mum friends have mentioned it, mostly positive feedback, though honestly ang bilis ng conception ay talaga namang variable from person to person kaya mahirap i-compare. One of them got pregnant on the second cycle of taking it, pero ang isa naman ay after a few months, so it really depends sa maraming factors like timing, health, and all that. If you're considering it, best to check with your OB first para ma-confirm kung okay for your situation, especially kung may existing health concerns ka!
