Ttc and getting negative

Kyra

I started a new birth control patch in July. Suppose to make me not have period for 2 months. Well I ended up getting my period August 22. My husband and I decided to start trying. So after my period was done we tracked my ovulation on a app. Yesterday I was 2 days late for my period. I have noticed this week I am exctremely tired, have two cold sorea(which is rare for me) and headaches. Yesterday i took a test and it was negative. Is there a way I am still pregnant?
