Scared and need advice?

All I’ve wanted forever is to be a mom. I recently tried for the first time so excited. About 4 days after I realized that maybe I’m not ready to give certain things up due to my age (22) and wanting to still experience life. I spoke with my husband about this and he understood. I took a plan b in hopes that if it wasn’t meant to work out it wouldn’t. Fast forward to today, I get three BFP from my first time trying. I’m numb to the fact but I’m still excited. I feel guilty for ever saying maybe I’m not ready. Could this be due to hormones, does everyone go through this?
