Anxious and nervous

Ha

I’m 4w2d & was confirmed via bloodwork today that I’m pregnant. My Hcg level was only at a 13 but she said it was a good number & they weren’t concerned. It seems so low to me. I’m getting positive dye tests but got a negative digital. This will be my 4th pregnancy with 0 successful. I’m so paranoid. I’m having twinges in my right side that almost feel like ovulation pains. I’ve heard they’re normal but I’m picking apart every symptom.
