Can somebody tell her.

Can anybody please tell my sister (cuz she's bugging) that I'm not pregnant! I took two tests both BFN after being 13 days late. I finally got my cycle which only lasted like 3 days but the first two days were heavy and the last day was on and off spotting ( normally 5 day cycle) today I threw up and now she swears I'm prego 😒😑 maybe if she reads yalls message she can stop asking me 50 times if I am.
