No period, Negative Pregnancy test.

My period is 5days late, and all the pregnancy tests i have taken says negative. I normally have regular periods always on time, except when I’m pregnant. I had a miscarriage in December 2019, so I’m concerned. I don’t wanna over react or overthink it too much, but that’s hard not to do. Has anyone else been or is going through this???? Any word of advise will be appreciated!!!!

UPDATE!!!!!!

My period came a few hrs after making this post. But since my miscarriage, my period seems to be coming later than the app has, I keep updating the app but it’s still off.
