Ectopic pregnancy or regular pregnancy

Hey guys. I’ve been feeling some annoying pain on my left side only for the last 3 days.. it extends to my pelvic, lower back and left leg. I got a pelvic exam done yesterday and they only told me that I have some cyst on my left ovary. Do you think they would have been able to detect an ectopic pregnancy through that ultrasound? Also I just found out I was pregnant today(5 weeks I guess) so they were not looking for anything like that. But the pain seems to get a lil more painful. Well annoying cause I can kinda bare it. Last thing, I’m just having a thick creamy white discharge no brown or blood
