Feeling harassed and stuck

So I will try to make this short as I can. I'm 32 and I work in a bar I've been bar tending now for 8 yrs. I've been at the bar I work at now for a yr in January, my manager has only worked in a bar/bar tending for only 3 yrs. She hates me she has done everything under the sun to set me up to be fired but failing with no back up to the head boss. I want to leave but..... me and my husband are ttc our 1st we need me to stay working until a baby comes. Soooo I could put my two weeks in and start looking for a new bar tending job, I'm also waiting (10 days in counting) to see if I'm pregnant starting a new job puts me at loosing money and then what if I find out we're pregnant then I'm really gonna loose money. So do I just keep going on at my job covering my self or bite the bullet and get a new job.
