Please help?

Before I start I want to say I do plan on going to my doctor as soon as he returns from vacation. Now I have a question. Does anyone else here feel really nauseas right before and the first 2 days during their period? I am afraid to leave my house when I feel like this. I've never gotten sick but I feel so terrible! Can anyone explain why if you also feel this way? Also what can I do to help it until I can get to my doctor? Thank you for any input!
