Can you pop a stitch at 4.5 weeks and when should you be concerned?

Felt a "snap" inside while bending over to put down a drink. (I guess I twisted weird?) I'm 4.5 week post- BA + lift. I'm out of town an wondering at what point, if at all, I should be concerned by this? I feel fine now (maybe, a bit tender there). Anything to be looking out for? Thanks in advance!
