Help?

I’m 6 weeks PP and I had sex about 10 days ago and the condom broke, but ever since this week I’ve been feeling off I’m not stressing the thought of pregnancy. But I’ll explain

I had a bit of one time light bleeding 3 days after sex but it stopped.

Then this happened

-I am exhausted more then usual

- get occasional headaches

-I feel just like I’m coming down with something

- dizzy and faint

-bloated in my abdomen

-nauseous

-food craving

-heartburn

-shaky

-acne everywhere

-my cervix became soft, high and closed

- have a extra amount of discharge and it’s thick and white

*But I took a test yesterday and today and it was negative is it too early to tell?

Also...

Is this normal for postpartum?

Or is there a possibly I’m pregnant again?
