Not feeling well, but is it normal? 33W+

So I haven’t pooped since Monday, like a full poop. So today is Friday, I’m getting ready for work, I decided I had some extra time to sit and TRY to go.

So at 5pm, I sit, I am not over pushing, but I slowly start to go.. I suddenly become very light headed, sweaty and weak like I’m about to faint.. I quickly finish up, because I feel like I’m about to take a header into the floor, I look in the mirror and I have NO color. I’m a damn ghost.

So I go downstairs quickly check the air, it’s low, 74 which usually would be cold, so I knew that it’s physically me burning up.

I lay on the floor in the kitchen where it’s cold, and get the orange juice and a cold water bottle out of the fridge. I lay on my left side after drinking, and hold the bottle of water to my chest. I’m not sure what is happening to my body.

Now, I come home from work.. I start to eat what is a normal portion of food and I’m feeling like I’m going to puke. My stomach is in my throat, and my belly is kinda in pain.. now I have severe nausea.

I don’t know if any of this is related, is it normal? Did I catch some kind of bug? What made me want to faint? Low blood sugar? Low blood pressure? Help. I’m scared of feeling so shitty while caring for a little baby still
