Previous C-section

Lily • Mommy of 2 boys currently waiting for my princess! Due Dec 7 2019
I had a previous c-section about 2 yrs ago and I'm about 5 weeks pg. last night I felt a bit of a burning sensation on my left side of my csection. And today it feels like I have something a little heavy in there. Btw I have a bikini csection. Anyone else can relate to this ?
