What is this?!?!?!?

So me and my husband don’t use protection. We aren’t trying to have a baby but we’re not preventing it. We did have sex during my fertile window this month. My period was due today and it’s not showing. Took a pregnancy test 2 days ago and it was negative. I haven’t had my normal pms symptoms but no pregnancy symptoms either. 🤷🏻‍♀️🤷🏻‍♀️ So I’m not sure what’s wrong with me?!? Is this just my period trying to come? I’ve never had this before. I don’t spot before my period.


Also these pictures were yesterday and today. And it’s like ewcm with blood tinged? Maybe my period is just running late?
