Isolated After Pains 5 days pp?

Christina • Fri, Jan 27

I am 5 days pp and had horrible pains in my lower right abdomen last night; today it is tender in that area but not too bad. I've only had mild cramping otherwise, so this isolated pain seems strange. No other symptoms going on. Any other mommas experience this? I was thinking it's round ligament pain. But my husband just mentioned appendicitis?? 😳
