Not necessarily squad! You don't know how a woman's hormones can go into overdrive when it is something you badly want! I have been convinced in the past I was pregnant after becoming obsessed with it, I had a late period a few times and 'felt' pregnant after doing tests and was sure the test was wrong and it wasn't. Ironically when I did find out I was pregnant it was a complete shock as I hadn't even noticed I was 12 days late!
louise, if you are stressing, please try not to I know it is hard, I hope you get the result you want but don't convince yourself you are just in case.
