Okay, so I started my last period on nov 4th and it lasted about 4-5 days which is normal for me. Hubby and I had sex like the day it ended and have had sex a few times up until today, we don’t use protection but he pulls out. We aren’t trying but we also aren’t preventing. Anyways today I went to the bathroom and when I wiped there was dark brown blood and I noticed it was in my underwear too. I put a panty liner on and this is what it’s looking like over the course of a few hours. Sorry TMI, but is this implantation bleeding? My period isn’t due until the beginning of December and I’ve also been having a mild headache on and off the last few days
