I had my last two at 43 and 44. I’m 45 and still have all appearances of being extremely fertile, even as indicated by recent bloodwork that assess such things. I am not typical, however.
For most woman, fertility seems to drop drastically after 40, and most especially after 43/44, so I wouldn’t waste any time. But it certainly is possible. Do you know what age your mother went through menopause? It’s thought to be a general indicator of the length of potential fertility, although many other factors also come into play.
Do you know NFP? I would utilize it to maximize your chances to achieve pregnancy. It will help you p(name removed by moderator)oint which days of the month are most likely to result in conception and read your own fertility signs. I conceived my now 2 year old using NFP to identify the best days, and it took only 2 cycles. If you haven’t learned NFP already, I’d recommend Taking Charge of your Fertility (TCOYF) , a easy to learn book on fertility awareness. It will help you QUICKLY learn how to chart and maximize the potential for pregnancy. I’ve learned NFP both through CCLI, and through TCOYF, the TCOYF is simpler and easier. TCOYF is secular, and it does mention that if you are trying to avoid pregnancy, an option is to use barriers during the fertile time, which is obviously NOT a Catholic option, but if you ignore this, it’s a very good resource.
Another book that may be helpful is Fertilty, nutrition and cycles which can give you some good information about the affect of nutrition/supplements to improve your cycles. For instance, B6 helps many women improve the quality and quantity (which can be problematic as you age) of cervical fluid which can increase chances of conception. It can also increase the length of your luteal phase, which is helpful if you have a LP that may be too short to support implantation. B6 has a dramatic effect on my cycles.
Best of luck to you and your husband!
