Just wiped and got this 😞

Not sure what to think. My first pregnancy. I’m 5 weeks and 2 days today.

Earlier today I noticed some very light brown spotting when I wiped. When I got home from work 30 mins ago, I wiped again and it was a light pink color but small amount.

Well, I just wiped and got this. I’m full on freaking out. Because it’s just progressed all day.

I have had on and off cramping today. It wouldn’t normally alarm me, but all these symptoms combined has me worried. Especially because it’s continuing to darken and increased in amount.

Opinions?? I’m already thinking about the dreaded M word 😞 do I need to call my OB in the morning?
