Conceiving questions?

My husband and I have been trying to conceive for a while.. We tried for about 6-12 months with nothing so I got back on the pill due to let down after let down. Recently we got pregnant and miscarried as fast as we conceived due to my blood type.. I got the shot needed to make sure this doesn't happen again and now the sex is just boring... It's like OK I need your baby juice and good night.. How do we still keep it fun when we're doing it everyday to try and conceived!?. Any insite would be helpful
