What the heck??

So I’m supposedly 5DPO which I had my peak on the 5th and I had pink stringy vein looking streaks of blood in my discharge but my period isn’t due until the 19th could I be trying to start early?

Sorry if TMI but I’m a bit constipated and after a harder BM I just had some darker color in my discharge almost purple but only a quarter sized amount like with slight cramping but the cramping could be due to my BM. The scary part is coming rather I start my period or not 😣
