Becoming impatient 😔

I’ve been on this TTC journey for well over 18 months, we are both in our late 30’s but have tried to take a ‘casual’ approach as not to increase both mine + my husbands stress however, it is trying my patience that he seems to feel sick/stressed/tired on/around my peak ovulation each month. Of all the things we (women) have to do to TTC (eat healthy/remember to consistently take prenatals/test BBT, OPK’s/lose weight), is it too much to ask that our partners take care of themselves in order to up the chances? This month the problem was heartburn/acid reflux. I’ve starting to think there is a pattern emerging and so I said something.

I pointed out that there might be a re-occurring pattern to his health that cause us to miss TTC at peak times but he doesn’t seem to think there is anything to it other than coincidence. I told him that I thought it might be his subconscious raising un-spoken doubts about TTC to the surface, he laughed it off and has told me many times that while it scares him a bit about becoming a father he does want children and he does want to TTC but also has mentioned we have plenty of time because he has guy friends in their 40’s who are still having children (their partners are in their late 20’s early 30’s and it’s their 2nd/3rd/4th child ).

What can I do you guys?
