Pregnant and resenting baby

I am 9 weeks pregnant (this is my first baby that i will have) and ever since i found out i was pregnant i wasnt that happy. My husband and always wanted kids and this was somewhat planned. I am starting to resent my unborn baby. I was not feeling excited like new moms out there. I see all the negative over the positive. I am afraid that i will resent my baby once its born as it will be a lot of responsibility on top of all the other things i have to take care of. I am afraid that i will treat my child with hate as i had a bad childhood with my angry father. I feel that i was excited before being pregnant and now that i am, im upset and crying every so often.

Can anyone give me tips or tricks?
