Worried about having another ectopic

I had one back in 2014 and I went on to having a healthy pregnancy a year later.. but I just found out I’m pregnant with my 3rd and I’m just 4 weeks.. but I have been experiencing dull aches and twinges on my left side... I don’t have any spotting and my lines on my pregnancy tests have been consistent. The ectopic I had back in 2014, I had spotting and my pregnancy tests would fluctuate from dark to light ... so I guess what I’m asking, is it Normal to cramp or feel more on my left side than my right ?? Has anyone else experienced this and it not be ectopic??
