10 days late

Kat

So I’m 10 days late. My bf and I used a condom and he pulled out. I took 2 tests 2 days apart after being late a week, and both were negative. I did have a fever on the first day I was supposed to have my period, but idk of sickness can throw it off. Help?

Update: I took a clear blue test yesterday and it was negative again. Took some Vitamin C and my period came overnight. Yay!
