Confused....

So i had my first pregnancy & MC 2 months ago now. I found out i was pregnant 10/1 & MC shortly afterwards 10/8 i was 5wks 4days. I spotted from 10/8 until 10/21 when my MC went active & my OB said i could count that as my first cycle. So after AF i went back to spotting from 10/26 until 11/12 the spotting stop for a few days witch i think i ovulated and may have caught it. Then the spotting start back up on and off from 11/18 until now. My period was due 11/18 im normally 28day cycle & bleeding for 4days. My period still hasn’t started. Just last week I felt pregnant, i had a few of the symptoms i had when i found out the first time. But just 3 days ago it all went away so im not sure if i was or if I wasn’t because my test from my first pregnancy was still giving me false positives. My digital is still showing false positive but my dye test are getting super light. So my question is how would i know i needed a D&C? Im not in any pain I don’t have any foul smell or discharge. That’s anything I don’t have any discharge either in between the spotting. This is week 6 of no period & still spotting off n on. Today marks me being able to announce my pregnancy I would’ve been 14weeks... 😪yesterday was hard just thinking about it....

Questions: How long did you spot? How long did you go without your period? & how would i know i need a D&C? Thank yall so much. ❤️
