Hello beautiful ladies :) I have a little predicament...

My period started on the 28th of September and I started the pill on that day, I'm taking Yaz. My period usually lasts 5 days and its gone on the 6th, but this time it kept going after the 6th day but really light. No cramps anymore or any symptoms i usually have on my period. And the blood doesnt seem fresh and reddish like a usual period, more brownish but I think its mixed with some cervical mucus making it difficult to tell what the blood is actually like.

Now i had sex this thursday (5th of october) and there was no gush of blood after and there was no mess during. On that day i think the bleeding was actually less than today. Its not profuse or really noticeable at all but it does fill my pantyliner everytime (i use the really light paper thin ones).

Did anything like this ever happen to anyone before? Should I be worried?

Thank you :) xxx
