Ectopic pregnancy? Or mi imagination ?

This is my 3rd pregnancy which is why I'm so scared and frustrated... I had nexplanon removed on March 22 had a period for five days 3/26 to 3/30 .. and now I'm 5 weeks 4 days ... I've read so many stories of miscarriage and ectopic pregnancy when is so close to implant removal... i had it for the whole 3 yrs also it was the first time I used a birth control ...

i been having lots of pain in my back and also cramping a lot ... yesterday and today i have a slight pain in my left side but than I feel like I have pain on my right side as well ... I have no symptoms no nausea vomiting only frequent visits to restroom .. I have an appt until may 15 but I'm stressing so much just reading and thinking something is wrong 😒😒 I didn't have these issues in my past pregnancies

any experiences? Any advice for discomfort?
