This is the fifth month of TTC. I have been feeling sick on and off since about three days after ovulation (about 12 days ago). The first time I was pregnant I didnt start to feel sick until about week 5 so I think its unlikely i would start to feel sick this quickly. I dont really have any other symptoms except for an ache at the bottom of my back. Maybe I've just got some low grade bug but I do keep wondering. Has anyone else felt sick almost immediately and found they were pregnant?
