I am 15 and maybe pregnant................?

I may be pregnant but I cant go to a doctor or get a HPT because I dont want my mom to find out just in case im not..This was a total unplanned pregnancy and i was in shock when i started get pregnancy symptoms..Nausea, Bloating, Eating alot, Dizziness,Tiredness, Constipation and Calf muscles are sore..But i told my friend i may be pregnant with his baby and he said have an abortion but i dont want to kill or give my baby up..! So should i just get a job and raise it on my own??
