I feel very sick 6DPO

Tess

I should be about 6DPO today, my tummy was painful it felt like my belly button was being pulled and before I slept my lower abdomen was shivering or kind of trembling. I was so hungry during the night and didn’t wake up and felt pressure in my head. Could this be an early sign. Now it’s 6:59am I made a bowl of cornflakes and I couldn’t even eat them but they were what I was craving at night it seemed they had a funny taste so I just had a few spoons and left it. My whole body is feeling cold like from deep within i even have a hot water bottle in the blankets and wearing 2 pairs of winter socks( my feet are very hot no matter what the season I can sleep with them in the blankets for like a few minutes and I take them out of the blankets due to the heat and I never sleep with socks on ) oh and I feel dizzy here and there what is going on. Is there anyone who had these symptoms and got a bfp
