I am a total nut job.
I too need to relax about it. I am getting pretty good. Until the last few days of each cycle, when I get really nervous and tense.
I vary between thinking that there is a baby out there for me...and thinking I was something horrible in a past life and now this is karma.
I too thought about the magic marker thing - only I thought about outlining my nipples to see if they got bigger.....:LOL
I am not as obsessed as I once was. Once I got over that year hump, I sort of realized that this was going to take a while and that I needed to chill about it. the first few months of ttc - I was a wreck...did we do it at the right time? Is that ewcm of something else? what the hell are my charts doing? now until I get to that last three days of each cycle....i am fine. I take my meds, chart and so allt he things I am supposed to and like knowing what is going on. But once I get to the last few days...eeek!! Then I just come on here and let you all know about what crazy thing I am thinking this time.
Funny thing is - I think i am going to truly FREAK OUT when I actually get pg. Just because this whole ttc thing has become such a part of me, such a way of life. This is routine, just what I do every day. And because i will have to work through all those "holy crap I am going to be someone's mom!" things too.
So basically this was a long way of saying I hear you and completely understand.
As for coping advice...no. I try to not think about it. I try to keep busy. I even didn't log in to MDC for two days once to keep from thinking about it. When I actually am busy, I don't think about it. But it is hard to keep that busy all the time. Smile, indulge your little obsessive moments and then have a nice cup of tea and move on. I think that the more you try to keep yourself from obsessing, the harder it is...like saying, "don't think about pink elephants."
we are all here for you!!! vent away when ever!
