Feeling rough

Can anyone offer any advice. Every morning I'm waking up feeling nauseous and with mild period pains. Most of the day I'm uncomfortable and I am SO SO tired. I have spent the majority of the last two days in bed. I'm 38+4 and I am so ready for my little one to be here now. Shes all in the right position it's just a waiting game. Anyone got any tips to make me feel better or why I'm feeling like this? Or even if you're feeling the same!!
