Rainbow baby so soon??? Help

Omg omg omg!!! My first pregnancy was in July I lost my baby at 6 weeks. No d&c but after 2 weeks when my cycle started in August that's when the tissue ect.. Came out. My AF was due on the 19th but nothing. I feel the same symptoms as before except for the major implantation cramps I had before at around 4 weeks. The other thing is we had sex several times but the day before my AF was due he went all the way 😉.

Help I'm happy if I am but bracing myself if I'm not. But is all this possible??
