Am I going to lose my baby?

Alexis

So couple of months ago I was diagnosed with endometriosis and I’m having surgery to correct it in the next couple of weeks. I been have a period every month since I been diagnosed but I’m 7 going on 8 days late. I took a pregnancy test and it came out negative. I then started googling and it says it could possibly be a ectopic pregnancy and that it won’t show up that I am pregnant on the test. have anyone dealt with this? Am I pregnant? Am I going to lose my baby? Should I go see my doctor and get a ultrasound or pregnancy test done? Should I wait more days for it to come on? I am so scared and freaking out! Anybody’s help or advice will b greatly appreciates! ❤️ thank you in advance
