No pleasure

It started of two weeks ago when my hubby and I were intimate and I just didn't feel anything no pleasure, nothing. Days later we did it again and that time I did feel but last night it happened again. I felt no pleasure, nothing. I'm starting to worry what if something is wrong with me. Idk if I should go to the doctor or what should I do. Sex is a big part of our marriage. I really miss the feeling. I need advise on what I should do or what can be happening to me.
