Is this normal for me to feel this way?

So Friday I gave birth to my beautiful little girl 💕 but since then I have felt like I have a cold (just started feeling this way) my bones are achy, I have a small fever of 100° (I checked baby girl she don’t have a fever) and I’m staying chilled, with a headache.

Could it be dehydration? I’m breastfeeding rn as well (which is why I checked her temp.) I’m a ftm so I’m freaking out over everything.
