Hi Erica,
It increases your chances as you now are ovulating and if your eggs are 'harvested' then you will have more than one. The risks of multiples are really not as increased as many would think. Many women with PCOS don't ovulate, therefore, when they do take drugs to stimulate this, they tend to produce more eggs on each cycle they ovulate, as opposed to your hormones causing this.
You just could release multiple eggs in one cycle or just ONE actually. That said, many times the multiple eggs produced are not all in the best of shape in terms of morphology(shape) etc., and would not be considered viable to be used anyhow, so even with more eggs, the odds could be much less than a woman without PCOS or yourself producing one good , normal egg, that splits into two =identical twins.
Erica, remember as well that if you or your spouse have twins in the family genes, the possibility of you having twins regardless, remains a possibility, and would not be reliable to base multiples on your condition or as a result of the drugs you are taking . Overall, I believe there could be just a bit (miniscule amount) of a heightened possibility of increasing your chances of multiples, but as I said...it is extremely minimal..I am sure you have talked with your doctor about this concern(perhaps you should again to alleviate or be resolved with the possibilities).
I have a cousin who is 48 and just had a baby, similar history, was not ovulating at all, tool clomid and metformin for a while, did several IUI's, and and IVF with the injectibles, had an ectopic, had to remove one of her F.tubes, and took 6 months off just to recuperate and give her body a rest, froze the embryos she had left (BTW...her egg harvesting /retrieval produced 17 eggs! thats plenty. In the end, the first IVF the Dr. actually implanted 3..Did not happen, then the ectopic, and I suggested she froxe the last 2 viable ones that were left over. Guess what? it was so worth it! The two were implanted and baby Caleb was born! He is 3 mths and cute as a button!
She was more terrified of multiples...it is not that common...I would not worry about that. Focus on getting pregnant. If it is really concerning you, then speak to your doctor to look at other routes and options to have more control over what is done. For example, retrieving your eggs, and deciding how many to place inside your uterus(again, this is not reliable...He/she could place just one which splits into 2, 3,...not to scare you but to make a point....he could place 2 or 3 as in my cousin's case and nothing, or he/she could place 2 and just one will make it. Then you have Nadia Suleman? She wanted multiples...and what happened to her is not the norm? The odds are very slim that all 8 would be viable. In her case they were, which is why the CDC has guidelines for this.
Some women, do want multiples, so they will be implanted with that many(should not happen like I said as per the guidelines), however they see it and the Dr. as well as 'increasing the chances' of at least one being viable. It is very hard to tell Erica, and I believe you should as you are doing concentrate on staying healthy, following your Doctors' orders, and the rest will fall into place. You will get too much information, which can be a bad thing...Information overkill' or 'overload' ..It's a great think to be knowledgable, it is very empowering, but especially in such delicate issues, I would just be and stay as well as you possibly can under your Dr's orders, hope, keep faith, and all will be well. Everyone is different, every woman's body is very different, so what will work and what happens to one woman even under the same conditions, will and could be very different in your case. Just remember that ok? Until then stay healthy, be beautiful and I am sending you lots of hope and baby dust ok?
Hope I have clarified at least a little bit..but do speak with your Dr. about any concerns ok? Be well Erica! As always, keep us posted. ok?
Dr. J
