Ectopic pregnancy

Hi ladies I’ve had an ectopic pregnancy years ago where they had to remove a tube, now I just found out I’m pregnant about 6weeks and she told me just to be alert since I’m prone to ectopic pregnancy. Only concern is I feel a side/back pain that comes and goes. It feels mild and passes but it’ll happen for awhile. Is this normal?

With my ectopic I didn’t even have the slightest clue I was pregnant and one day I woke up to horrible pains where I was in a ball crying. I don’t want to catch it when it’s too late but I also don’t want to be paranoid.

I must add, I found out at the clinic and she told me it might be too soon to see in ultrasound to go in a week or two..

Thank you
