Nervous ?

Me and my boyfriend are planning on having a child, but not yet. This morning i started throwing up, i have very tender breasts, and my entire body aches. We have been having inprotected sex, but ive been on the pill faithfully for about 2 months now. Im scared that if im pregnant, hes going to be angry because we already had a plan for that. And im scared hes going to think i trapped him because hes had it happen to him before. What do i do? I know hes going to react negatively to it, only because we arent entirely ready yet.
