Pregnant and bleeding

ja

So within the past week I've found out I'm pregnant but yesterday started off with very very light pink spotting then brown spotting then overnight in became a little heavier today still spotting... Just very nervous this could be a miscarriage I don't have any alarming symptoms just bleeding I'm assuming I'm very early app says 4w 5d but wasn't <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> ... These are my test from this past Tuesday when I found out I was pregnant along with my calendar

Here's a test I took the day before yesterday

Here's a digital I took this morning

And this is how I'm spotting/ bleeding today .. I kinda feel like it's my period but no cramps or pain.. I feel absolutely normal besides the bleeding , flow keeps varying
