Too early to say...

Holly
Ok, may be totally in the mind but..
We did the deed last night, no protection obviously as we are ttc...  But today.. I am feeling very very sick.. Massively nauseous. 
Could it be too early to be? Like I've said it may be in the mind, but that feelings been there most of the day. My next period isn't due for at least another 2 weeks!!
