I feel like crap 😭

Guys the past few days I feel like I'm getting over the worst part of the flu, i havent been throwing up or anything, but I've been so tired, my body aches but like a dull ache and I just overall dont feel well. Baby is fine, his favorite is when I'm trying to get comfy after work, then he is moving all over the place. But I'm so over feeling like this, is it normal? I heard babys heartbeat yesterday again and it sounded just the same as usual, so I'm not too worried about him, though I lost my first baby at 10 weeks, so I worry over little things. Other than that it's just the usual, hips hurt, back hurts, tailbone hurts, having a harder time getting out of seats lol. But is it normal to feel like this? I'm 19 weeks.
