Too soon??

I had a MC on sept 22 and was 5w4d. AF came on October 23. I think it's too soon to test but I feel like I did right before I found out I was pregnant the first time. Is that even possible?? Could it happen again that quickly??  I think it might be all in my head because I'm wanting it to happen
On another note, has anyone made you feel bad for being sad over having a MC early on?? My doctor made it sound like no big deal because most women don't know they ar pregnant that early on - all this coming from my very pregnant Doctor! 😕
