Then went to the doc and took one she said I am not pregnant but I haven't had my priod in a month going on 2 so could I be pregnant do I have to take a blood test to see if I am pregnant are not what should I do it feel that way my belly is looking and feeling big can't get into nothing no more

You might want to have a blood test done to actually confirm.

It's pregnant, not preant.

I would be surprised if you are so "big" in going on two months that you can't fit into your clothes BUT go back to the Doctor and ask for additional testing. If you are NOT pregnant the Doctor should be checking to see if there is another problem.
