Long story...but...thoughts?..help?

So I'm on the pill...but I don't take it perfectly. I don't take it for its birth control reasons but more to reduce period symptoms. Whenever my boyfriend and I have sex a condom isn't used so pregnancy could happen.

A week ago now I had some pink discharge and got excited that it may have been implantation bleeding. We aren't really trying right now but we wouldn't mind.

I had taken a pregnancy test a week or so after and I'm not sure if there was a second line on the test or if I was just hoping to see one so I did kinda thing.

Today my period started but it's pink....not red. So I'm thoroughly confused. My plan was to retest first thing tomorrow since my period was due tomorrow but this has thrown me off.

Update: Conclusion....a weird period
