Would I know if I was 2 months pregnant

Would I know if I was 2 months pregnant by now without any tests.. i took 6 in total I had sex April 30,2017. All the rest I took came back as negative. I have nexplanon so I don't get my period from that.. but when I suck in my stomach it hurts i don't know if it hurts because your not suppose to that or what.
