Hi, I had the shot (depo provera) for 1years and my period never really stop. I stop the shot the 1 april 2021 and since them I had my period like 3 times and I know its normal Im not regular but this time im 18 days late. My husband and me have regular intercourse and we don't use protection. I do regular pregnancy test and it always negative but im still scared it can be false negative. Should I just wait and stop stressing with that?

Ps: sorry for all the fault I normally speak french😋
