Too much exercise and ttc

[Challengethisweek]

Hi ladies,
i should be ovulating this weekend but also doing a challenge where I will be doing 15 hours of medium impact exercise over the weekend. We wanted to start ttc this month but I wanted to wait till after this was over, as I had heard over exercise can increase the chance of mc and make it hard ttc ( according to google) I normally do 4 hours a week of exercise at the most.

So have any of you have experience exercising lots and ttc? Or advise?
Would doing a one off big exercise effect my eggs or chances or is it just those that do it regularly?
:) thanks in advance!

I really wouldn't worry about this.

I run around 50k per week and have done so until 11-13 weeks of my successful pregnancies. Medium impact is the key, and if you are oly trying to ttc I would not worry about anything at this stage.

I looked at the research on this a few months ago so might as well share what I found - basically the only way exercise should affect TTC is if you are training so hard that your periods stop. That could possibly happen while training to do a marathon or triathlon etc, but you would know about it (because your period didn't come!). It can happen to female athletes but it's usually reversible as soon as they stop being so hardcore. It happens because when you are training really hard over a long period, your body's metabolism really shoots up, and a consequence of this is that the hormones which regulate your cycle get metabolised very quickly. This means they aren't circulating around the body for as long or in such quantities as normal and so may not have the effect they usually do; so eg if the LH surge which triggers ovulation is much lower than normal then you may not ovulate. As soon as your metabolism goes back to normal your cycles should too.

So if your period is still regular, you're fine. I guess there's a possibility that a short period of very intense activity could delay ovulation while it's occurring, but once you go back to normal it will happen as normal. I doubt 15 hours of "medium impact" exercise would fall into this category.

So basically, carry on as you were!
