First pregnancy

Sandra • 💑 Baby G due Feb 14❤️

So I got my BFP 4 days ago. I’m about 4 weeks along! My main symptom so far is cramping. I’ve heard this is normal because the uterus is starting to expand.. right? What worries me is that the cramping is always on the left side, rather than generalized across my whole lower abdomen. Should this be cause for concern? The cramping is very mild but has been happening on a off for a few days. Thanks!
