I am not suppose to start until the 31st or Feb 1st. Friday my husband and I dtd and I ended up bleeding but it was brown. I was shocked because I don’t start 12 days early...ever! I cleaned myself up and then nothing more happened. Then today I had a very very slight brown smear and then nothing. I took a test but it’s either vvvvvvfl or nothing. Does this sound like implantation bleeding? Also, I’ve had the munchies like I do a few days before I start. Thank you for any advice.
