Ok. So... This cycle was very odd. My fiance and I are not trying/ not preventing. We had sex during the right time and everything. At 5 dpo, I started spotting. It was mostly brown with some pink and carried on through 10 dpo. At 11 dpo, it got heavier. I'm sure it's just my period, but I read about decidual bleeding. What I have sounds just like it, but I'm sure it's just my period. I really don't want it to be. Has anyone had anything like this? My periods are usually regular and predictable. I think that's why I'm questioning so much.
