Hello! My husband and I made love the week when I was ovulating. Yesterday, 8 days after that and 6 days earlier than my next expected period, I started to have some pinkish spotting and at first I was hoping that it was a sign of implantation. But then it developed into a medium flow with bright red color. Now it is light again, the color is still red, but it's not too dense. However, there are no typical period signs that I normally get, such as sore breasts, mood changes or painful cramps. Rather on the contrary, there were almost no cramps (usually around 2 hours into my period I can't make it without taking pain killers and this time I didn't even have to take any). The only thing that is typical about this is lower back pain. I have read a lot about implantation bleeding and I realize that it is quite rare, but is there a chance that this could be it and I should just observe, wait and do a pregnancy test in a few days or chances are that most likely it is just a lighter period that started earlier than usual? Thank you for your advice
