Hi Shell, ttc is a rollercoaster, try not to get too p'd off with it, try also remember sex is great exercise, remember all the calories we are burning up when it's mission time.
seriously though, it is hard, sometimes, you feel it would be less hassle and you would be happier just quitting, i've not felt like that for a couple of months, but i honestly know if i don't fall by the time i get back from my hols, i will be devastated, especially as my best friend is now due her 2nd baby in exactly 24 days, and as soon as i hold that baby i just know i'll go home upset.
Good luck honey and you never know, this could be your month.
Pauline.
