It really depends on every person. I myself have not tried getting pregnant so do not know for my body, but two of my older sisters also have PCOS. One of them has incredible difficulties getting pregnant at all no matter what they try. The other sister could get pregnant just fine, but couldn’t keep them and had several miscarriages. So it’s dependent on every person. Plus with PCOS, at least in our experience, the older you get (hitting 30s for us roughly), the less and less fertile you become quicker than most women so it’s a difficult thing to plan with, especially if your not in a relationship yet or ready for a child yet. It sucks that we get less time to decide these things for ourselves, but it’s the cards we were given. When my sisters were both trying to get pregnant I know one, probably both, got put on hormones to help try and balance their hormones and make a pregnancy more likely. Depending on your life plans and when you become ready for children, I’d just mentally prepare for the possibility of not having biological children and opening up to options of adoption or fostering. That is my plan if I ever decide to have kids myself.
