I'm here for your opinions.

My boyfriend and I have been having unprotected sex for the passed couple weeks. He says that he wants me to have his SON because he is 24 and claims he's ready for a kid. I'm 21 with a 7 month old already BTW. We had unprotected sex over 5 times even around the time I was ovulating. I've recently been feeling "pregnant". My stomach has been twisting and turning, I sleep entirely too much now and my boyfriend as well plus he eats like an animal now. He and I believe that I am pregnant but I recently took two pregnancy tests and both came back negative. I did in fact take them too early knowing I was supposed to take them six days before my last menstrual period. Anyway that's besides the point. He is upset at the fact that I told him I'm not ready for another kid and that we've only been together 1 month, YES, 1 month and it's too soon for me to have his kid. I really like him and deep down believe he will be a great father and he'll be around BUT at the same time, I risked sending my daughter to Georgia (because of no support) to live with my cousin so that I can graduate from cosmetology school. He then states that I can be pregnant and attend school at the same time, which I know I can do but just refuse to do. I then tell him that I'm not ready for the critics and the negative options of others about me getting pregnant AGAIN after just having a baby and people looking at me some type of way because I risked sending my daughter to a different state to be focused and I know for a fact people are going to think I've just been out here taking advantage of the fact, and assuming I've been out here "having fun". Can someone please give me some advice?
