Am I Pregnant? Help

I am dating this guy for almost a month now. My previous relationship was last 3 years ago. I really like this guy. We enjoy each other a lot. We had sex many times already. Very often.

We tried to control ourselves and not have sex bc it bothers us both. We lasted for almost 48hrs with no sex.

Is there something wrong with having sex so often?

Now, i am worried. I might be pregnant. My breasts aches. It only aches during my period and now it bothers me. There are times that i feel full when im supposed to be hungry. I feel like vomiting but nothing came out.

I am 23 and building a career as an architect. I want a baby, a family, but not right, im not ready.

Please tell me i'm just over reacting.
