hi newmom! i don't think that i can really offer any help, but i can offer reassurance!
i've been ttc for 3 months now, too. it sounds like you're doing everything that we can do, but we just must be a little patient...please don't think that i don't understand, because since childhood, i've been a very anxious & impatient person myself.
I was very impatient the first month & somewhat last month & my 2ww always has it's trying days, but i've just realized i need to relax and enjoy the "ttc'ing phase" just as much as the "pregnancy phase" or the "infancy stagbe", that we just can't wait to get to. IMO, i think that the dp's love the ttc'ing phase, with all the bd'ing that we get to do!
from the reading that i have done, i've learned that on your chart, you should see a distinct rise in temp on the day after ovulation and it should stay elevated in that range indefinitely if you become pg; if you don't become pg, it will start to decrease near the time AF will start up. i think my chart shows a pretty "typical" rise, then decline before AF started up again. my af's aren't always exactly regular, either...usu. within 26-29 days. i'm also taking daily pre-natals.
best of luck & baby dust to you & all of us here!
