What’s wrong with me?

I finished having my first period after losing a child last month.( I’m not bothered by it as much anymore.) But I’m concerned, I usually have a high sex drive and get really excited when it comes to doing anything with my bf. but now, I don’t feel any drive whatsoever. I used to love going down on him, balls and all but even that just turns me off in a way. Even when he tries to please me, I don’t get really all that wet. I have to really concentrate on myself to make it happen. I haven’t fallen out with him, he is perfectly imperfect. But I just don’t know. It could be hormones, but what do you ladies do to get your drive back?
