Cramps at spotting at 12 + 5 weeks

I’ve had cramping pretty much every day through this entire pregnancy. The past few days have been particularly bad in the evening after dinner (which I figured was round ligament pain) bc i am starting to show and everything is stretching.

We had our 12 week scan a few days ago and everything was perfect.

I woke up this morning with some pretty bad menstrual like cramps (not unusual), nausea and a bit of a stomach ache. I went to the bathroom and when I wiped there was a tiny bit of brown blood.

Not sure how worried I should be. I have cramped on and off this whole time, so that part isn’t unusual to me.

Any thoughts?
