Rachel • Married to my better half, Mommy to a beautiful baby boy born 11/17/16, baby in Heaven MC 12/12/18, Baby girl Born 10/21/19.

Timeline

5/31- 2 bfps

6/1- started bleeding pink-brown when I wipe

6/2- still bleeding only when I wipe. pregnancy symptoms start (sore breasts, nausea, minor headaches, super emotional)

*Period expected*6/3- bleeding almost stopped i have very little bleeding almost don’t notice it when I wipe- still pregnancy symptoms

I won’t have more pregnancy tests until tomorrow, but I assumed I had a chemical pregnancy so I didn’t bother to get more until now.

What could this be?
