Hi, fellow severe PCOS sufferer here, beard, acne, insulin resistance and all!
I have a period about once every 6 months, my cycles can be anything from 26 days to 6 months long, so I totally get the infertility fear 100%.
However, you’ve been slightly misinformed. Although yes, a lack of regular cycles makes it more difficult to conceive, if you religiously track ovulation you have the same chances as anyone else, the difference is that you won’t ovulate as often as other women, so your chances are less frequent if that makes sense.
Over the last 2 years since DH and I started trying properly, we’ve become pregnant pretty much once every 6 months. Sadly until this last one, my pregnancies have ended in early miscarriage (nothing to do with PCOS by the way, all were blighted ovums). I’m currently 10 weeks pregnant with what will hopefully be our sticky bean.
We’ve managed it by ovulation tests 3 times a day every single day, temping and just getting to know my body at the time of ovulation, so now I can literally sense when it’s happening and confirm with tests. Have sex/ inseminate 2-3 times in the 2 days before you actually ovulate (just before or the day you get your LH spike) and that gives you the absolute best chance of conceiving. You’re right in that it gets harder as you get older, but that’s true for absolutely everyone.
I think what I’m trying to say is that yes, it can be a bit harder to get upduffed when you have PCOS but your diagnosis absolutely does not mean you’re infertile or that you will miss your chance if you don’t have a baby right this minute. I TOTALLY understand the fear though by the way, it’s overwhelming. Just don’t choose to get pregnant in the way you are if you’re only doing because you’re worried about the future, because the chances are like 70% of women with PCOS, you’ll be perfectly capable of conceiving naturally well into your 30’s and beyond.
As for your sister, you’re massively over thinking this. You don’t need to tell anyone what you’re planning if you do decide to go ahead, you could even tell folks it was a one night stand and you got lucky, how a baby is made is literally no ones concern but yours.
