Bad pelvic pain

This is my second pregnancy and I don’t remember having these pains this bad with my first. I know what round ligament pain is but I don’t remember getting it so early. I’m about 5-6 weeks but I’ve been having this really bad pulling pain on both sides by my hips. Like it’s so bad it hurts when I breathe. I don’t get it a lot, maybe twice a day. Is it just ligament pain?
