According to saliva ferning & CM details input to the TCOYF software I'm 3 or 4 days post ovulation (actively TTC). Last night at bedtime I started feeling really nauseous and was sick as a dog as soon as I got upstairs. Today I've felt absolutely exhausted (ok so thats not so unusual with a 1 yr old) and slept for about an hour and a half while DD napped. When I got up from my nap I started feeling quite queezy again, and all evening I've felt like I just wanna puke/sleep/all of the above (it's that seasick kinda feeling). When I was pregnant with DD I started feeling sick around 6-7 weeks until about 17wks. Is it possible to feel it this early on? Am I just being over-optimistic or have I maybe just eaten something dodgy? Any advice welcome.
