Ebichan, oh in that case can you get to sleep well for next 3 weeks? With the drinking that might go into the late night? Maybe prepare some ear plug or listen to soft music and put on a eye mask, before sleep.
For symptoms, I think preg and af ones are the same, during the 2ww. I feel really nausea for bfn cycles (progesterone playing tricks) and for bfp cycle, I almost felt not much nausea. So really have to pull through till missed af and test with hpt is safest bet. Good luck! Oh when is your next af supposed to be? Hope wont come though!
