Worried about another ectopic

A🤍 • Survivor of 8 miscarriages & 2 ectopic pregnancies ❤️

My tests from last week have all stayed the same faintness, they don’t get darker but they are lighter sometimes and then back to a little darker again but for the most part have stayed the same. Iv had terrible back pain that feels like a kidney infection and have now got small twinges in my right tube where my ectopic was the last time ( I didn’t lose the tube). I’m 5 weeks pregnant and obviously have low hcg due to the faint tests so they wouldn’t see much on a scan , So far I haven’t had any bleeding yet , I’m booked in for a routine ultrasound on week 6 but I’m so worried this is happening again. It was the most traumatic experience of my life … what do you think ?
