No sexual desire after miscarriage?

Two weeks ago I had a miscarriage, I was only five weeks pregnant but I was very excited about my baby. My boyfriend and I haven’t had sex since the day I lost the baby because I was bleeding but now that I’m not he’s been really touchy and says he wants to have sex but I feel no sexual desire at all. Nothing. To satisfy him I have been giving him blowjobs but I’m scared he’ll keep pushing and I’ll have to tell him I don’t want to have sex and he’ll be upset about it. Is it normal to not want sex after a miscarriage?
