pregnancy question?

I need help. Recently, i’ve been having unprotected sex with my boyfriend and the 5th of February i took a plan b (i weight 163). As you can see we’ve still been having unprotected sex but we use the pull out method (i know it isn’t ideal it needs to stop.) Yet, i’ve been scared because i might still be pregnant from the other times we’ve had sex (after the 5th). Would i start showing symptoms now? i haven’t noticed any plantation bleeding since then. All i know is that right now in suffering from a MEAN yeast infection, i’m scared, i don’t want to do abortion but my mom would kill me, kick me out, and i can’t afford a child. Although, personally i wouldn’t want abortion myself i’m not sure what else i could do. I don’t want adoption either. I want my baby. Should i wait until i get my period? wouldn’t plan b also delay my period as well? Please give me your thoughts on anything!! i know i’ve been really reckless about this. i’m 17 i don’t work but my boyfriend does. Don’t think that i haven’t been trying to get a job i promise i have just that nobody will hire me yet i know i’m so ready and capable at my semi grown age.

what date should i take a pregnancy test? if so that it comes out positive how much would be an abortion pill at planned parenthood?

give me your thoughts and what i should probably do or what you would do in this situation? thank you so much.
