Hello everyone!

I believe I’m about either 11 or 12 dpo today and since yesterday I’ve had a light bleed on and off continuing into today. I did have back lower back aches that went down into my left hip (more of the butt cheek area). I never really have these types of things happen. Only time I’ve had this is when I was pregnant with my daughter. I took a first response pregnancy test but it honestly looks negative. Anyone else experience this too? Thanks!
