So obsessed with TTC

Ever since my husband had also admitted he wanted to try for another child, I have been completely baby crazy! Constantly on the Internet looking up stuff about early signs of pregnancy since I had absolutely none with my daughter! An I can tell every month we get a bfn it upsets him. We haven't been trying for very long but I honestly didn't think it would be this difficult to get pregnant with a second child. First wasn't planned an just happened. But I'm not sure if I'm putting to many expectations on this or if I'm ok to feel this way. Sorry just needed to vent cause I'm getting on my own nerves.
