ok....now I'm looking for things to worry and obsess about

Its seems like ever since I left my job at the end of may......my anxiety has been on the rise.  I recently broke up with a guy who I dated for alittle less than a month and that is still weighing down my mind.  I met a new guy and things started looking up.  Then I started to convince myself that I was pregnant.  I went off the pill because I couldn't afford it without a job and I did get intimate with the last guy I dated.  We didnt practice the most saftest sex but we were careful.  I know....I'm 28 and I should know better.  Anywho....I realized the past week my anxiety has been bad due to hormones....since I was probably experiencing some PMS.  I honestly feel from the bottom of my mind and heart that I am not pregnant.  I've even started to have some signs of getting my period and still....I'm filled with anxiety.  Why am I doing this to myself?  I'm not sure I would handle it mentally if for some crazy reason that I was pregnant.  I had intercourse on sat night.....is it too soon to take a pregnancy test.  I feel like I'm slowly gonna drive myself crazy.  Help!!!  I'm embarrassed to even ask anyone like a friend about this.  I told my mom that I was feeling anxious and why.....but I feel so stupid and guilty for not being more careful.  I can't stop blaming myself and I can't stop the what ifs.  I need some kind words.  thank you.

You should take a pregnancy test. This will put your mind at ease. You have a lot going on with leaving your job, breaking up with one guy and dating a new one. Now this pregnancy scare. Slow down and start taking care of "you". It sounds like you've been neglecting your health. Take things slowly, find a hobby or exercise that you enjoy and I would suggest carrying condoms just in case. Good luck!
