Cramps and spotting!!!

Sh

I'm currently 4 weeks pregnant according to my <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a>. I'm also a high risk pregnancy due to type one diabetes. Well, I keep having light cramping that always feels like period cramps! It fades in and out, and sometimes will become sharp then fade away. Well the day before yesterday i noticed some very very light spotting, and then yesterday when I got off work there was a little bit of spotting again.It was bright pink and there hasn't been any more since those times. I've already called my doctors, and I see one of them on Tuesday but I'm just so concerned about making sure this pregnancy is healthy!! I've never been pregnant before so I don't know what is normal!!! Can anyone help me out and tell me if this normal or not??
