I recently found out I was pregnant after my menstrual cycle didn’t start.

The start date of my last period wasn’t July 31st, and had unprotected sex on the August 19th.
I took two pregnancy tests on September 1st, and morning of the Sept 2nd that confirmed indeed I was pregnant.

Symptoms:
breasts are tender/swollen
mild dull achy pain on the left hand side (somewhat lower) of my back
dizziness lasting up to two hours multiple times throuout the day
Nausea
Mild Achy pain in my left shoulder
Moderate/severe achy pain radiating in my left thigh
Distended lower abdomen
Extreme fatigue
Mild abdomen cramping

I am not spotting.
I did have a manual vacuum aspiration abortion 5 years ago.
I have had an STI on the past two years.

My concern is that this is an ectopic pregnancy, but I can’t tell if I’m overreacting or not.

With those symptoms should I go to the Emergency room?
