[mommy237]

So according to my ovulation calendar which may be off a little I am 6dpo I have been nauseous a few days and lastnight I threw up...this morning I have this cramping feeling on the right side of my abdomen and I have been really drained...is this common at this point. My cycle went off the March 29th and we bd'd on March 29th....April 1,2,4,5,7,11...is it possible these are pregnancy symptoms. I haven't been pregnant in 6 years so I really don't remember the beginning stages
