question about round ligament pain?

I'm 14 almost 15 weeks pregnant and yesterday had a dull constant achey feeling in the center of my lower abdomen around my bikini line. it's a lot better today but still there faintly. is this round ligament pain or should I call my doctor? I know round ligament pain is usually felt on the sides near the hips so curious if it can be felt in the middle and as a constant dull ache for a day?
