I can relate to a lot of what you are going through. I am currently going through infertility treatments b/c my husband & I haven't been able to conceive after trying for more than a year. I do the ovulation tests and take my temperature every day with the basal thermometer and have been for a few months now. Both the tests & temp taking are big helps in knowing when you ovulate which doesn't necessarily happen on day 14 even if your cycle is exactly 28 days. Personally I have been ovulating between day 10 & 11. It's different for everyone.
I understand your side and your husbands. For my hubby it was harder for him to "perform" when I started doing the ov tests and temperature tracking b/c he felt a lot of pressure. I have a feeling that could be the same for your hubby. Now our agreement is that I don't tell him when it is the "day" and he is happy with that. Although the men don't realize it, the whole process is much harder on the women- emotionally & physically. It's your body and every cramp or spot of blood makes you over analyze and it starts to consume your life. For me, my husband is incredibily supportive and wants a baby as much as I do, but he still doesn't understand the longing to be a mother & everything we go through (our bodies as well as emotional). Have you talked to him about the concerns you listed in your post?
The biggest thing I have learned throughout my troubles is that it is an incredibly frustrating & emotional time. Everyone tells you to "relax" and "it will happen when it's meant to" but when you're trying (and not succeeding) that's the last thing you want to hear. Although you have had some health problems, I think it is reassuring that your OB said your reproductive system is healthy. You also have time on your side since you are 23 (I am 31 and infertility runs in my family). Maybe the compromise with you and your husband is to do the temperature tracking so you can learn more about your cycle but not the ovulation tests at this point. Honestly I don't really need to do both because the two have been giving me the same results anyway. But your hubby doesn't need to know that!
