Yep I second buggerlugs comments, you do belong here (I did not see your other thread either, will go see if I can spot it in a minute).....
As for shorter cycles, nope, nothing to do with being perimenopausal, I have always had short ish cycles, never been a problem, my cycle length has changed after some pregnancies. But before I was ttc, my cycle length changed in my 30's, I went to my gp about it, he said it was normal for cycles to change a bit at that time. All the googling ! I have done seems to back this up, and unless you have been and had blood tests suggesting you are coming to the end of your fertile time, you don't need to worry about shorter cycles like you are getting. Just think of it as more opportunites to possibly get preggo, and maybe a miracle occur.
I am still trying to decide whether to ttc again. We are trying to apply to become foster parents, and I don't think ttc and fostering really go together, so I have to make a decision I think. However with all the m/c's I think my decision can only really go one way. So I am trying to get my head around what type of contraception to use. hey ho!
Sorry you are feeling dispondant, if I thought it would help I would do a jig around here dressed up as the tooth fairy and sing puff the magic dragon at the same time for you, but somehow, I am not sure that would help!!!!
