Do i count miscarriage as cycle on period app?

Ashleigh

Oct 29, 2018 to Nov 4, 2018 i had a cycle and then i didn’t for 38 days! I had sore chest and i felt sick every single day. I took pregnancy test and It was a faint line! Multiple ones. So i went to the doctors to do one and at first the gave me a pee test and they said negative, if anything i have blood in my urine. So i was like what? And got a blood test done. Before the results came back i realized in the bathroom i was bleeding. Like a period. This is Now Dec 6, 2018. The blood test came back negative as well. Ive been confused SINCE! Miscarry? Just a late harsh period?

My cycle was dark almost black or brown blood. Crazy cramps. After the first day of bleeding i no longer felt hurt chest or sick. December 6, 2018 to December 10, 2018 i was bleeding .

Miscarry our cycle ? Very late cycle?
