Well, not really...I mentioned it to my GP when I was in for my annual, I think back in the summer...she asked if I had been charting, so when I said I hadn't she just said, "Oh, it'll happen. You haven't had any problem getting pregnant in the past, so there's nothing wrong with either of you."
Which is why we're now at cycle 20 with no BFP...cause I've been thinking the same thing the whole time!!
In our whole marriage, we've always just kinda NTNP though, since we've never used BC. I never get my period back after BF until the newest one is nearly two, so the spacing is good anyway. I'm not really sure what happened after my third dc, as my cycles previously have ALWAYS been spot on 28 days. I don't know when I usually O'd but I just had in my head that it was around mid-cycle. Anyway, now with my cycles being 23-25 days, I decided to start charting in August. Then I ran across something on FF about short luteal phases, and the egg not having time to implant, etc., etc.
I actually thought I was pregnant a couple of times over the last year, and who knows maybe I was and the little beanie just didn't have enough time to dig in before my body expelled it?
Sorry for the rambling, but that's where we are now. And a little testimony if I may...there are plenty of areas in my life where I lack faith (way too many!!), but for some reason God has given me the faith to absolutely trust in His sovereignty over this part of my life. They are His children that He loans to me for a time, and He knows when it is the right time...and I totally believe that. So, actually 20 months sounds like a long time, and I couldn't believe it had been that long when I calculated it, but actually this is only the second month that I've even taken a HPT. When AF comes every month, I am of course a little disappointed, but then I turn around and thank God for His perfect timing, and for the three blessings He has already given me.
I know there are people who try for years and years for just one child, (I know a few personally, and may He bless those of you on this board that are in this position) and it is so heartbreaking to see them go through that. So I would love to have a fourth, but I also would be absolutely content with the beauties that are sleeping upstairs right now.
