My dh and i tried for a little over a year off and on (more on!) and we were able to conceive without the doc. mine too asked for temp charting and so i did and i think that really helped us to get pg, because i was starting to learn more about my cycles and when the best time to bd was and all that good stuff. I also took vitex to help my af's become more regular and drank green tea to produce more cervical fluid and all also did OPKs for the first time and that very same month i actually got pg and am now 7 months pg. And we are both young and apparently healthy, i am 21 and dh is 23, so you can have problems no matter how young or old you are.
Many couples take longer than "normal" to conceive and some couples need some extra help and there is nothing wrong with that. It doesnt matter how your baby gets here:)
What helped me to remember to temp in the morning was a huge note i taped either to my alarm clock or to my bedside lamp. Also i just kept reminding myself of how much we wanted a baby and that i needed to do what i could to make that happen. I know it is hard but once you start you'll start getting used to having to do it. I do understand about the pressure, and its easier said than done to suggest trying not to think about it so much when everywhere you look there are pregnant women and babies. I understand it all too well. Maybe a nice little trip with your dh to cheer you up would be good for you? Thats the reason my dh and i took a few breaks from ttc, cuz the pressure was hard for both of us and we just needed to focus on other things for a while.
I hope all goes well for you and that i have helped you in some miniscule way;) Take care and good luck! keep us updated!!
