Maybe baby?

I haven’t had my period for a little over two months and my boyfriend and I don’t use any form of protection whatsoever. We aren’t actively trying for a baby, but we aren’t trying to prevent one either. We both work full time and have our own home. We’re ready, but upon taking one negative and one invalid test it was an eye opener that we really aren’t. How do I open the door to discussion about wanting to get on birth control with my boyfriend?
