Ok, I have been with my partner for a really long time and we have been trying to conceive for over a year but have not succeeded. A couple of months after trying to conceive and having stopped the pill my period started changing. For example, I used to get my period every 5 days and now I get it every 6. I used to get my period every 28 days and now it fluctuates between 26-29 days. I have 10 days before my missed period according to my PT tracker and today when I went to the restroom I noticed some bleeding, it looked about the same color as my normal period, maybe a little bit lighter. My sister is on her period at the moment, I understand some girls periods sync when they spend a lot of time together or are close, I am rarely home and am not close to my sister. What does me getting this sort of bleeding 10 days before my period mean?

I've spotted brown 2 weeks before, 7 days before, the day before I'm supposed to get my period previous months. This month it's different, its more bleeding than usual and it's red with maybe a tiny little bit of brown, compare to other months where its more brown than red.

Can anyone tell me what's going on? I've been trying to get pregnant and have gotten exited before thinking it was implantation bleeding but no luck. :( I am 22 btw in case that makes a difference.
