warm baths?? 6 week contractions??

Shailee
I've been hearing a lot of strange things lately so I wanted to know. 1) can I take hot baths or no, Luke warm only? 2) are these pains early contractions? The doctor said I was fine and the baby is healthy with a little heart beat. I am 6 weeks and 3 days today. Are these pains just contractions? Feels like cramping in the lower stomach and vagina area. Please help. (First pregnancy)
