Hi e tan, I too have the same symptoms as you, but I got a feeling I might not be preg cos in 2009, I got a very quick postitive 2nd line once I missed my menses for a day but now I missed for 2 months but in the end, Doc say I too stress, that y menses delay. And Doc say normally, if you missed about two days of menses, the 2nd line will be fade pink, if no, think it's better to seek gynae's advice. If test still negative, mean you are preg and the doc will prescribe you med to take for your menses to come.
Hoped this helps you.
