Braxton Hicks?

I’m 33 weeks pregnant & I’ve had 2 experiences within the past week where I felt as if I could be having Braxton Hicks or just round ligament pain. The first time I felt it was when I got done cleaning my house, I noticed I felt pressure / tightening in the bottom of my belly under my belly button that went all the way down to my lower stomach (lady parts area). It went around to my lower back as well. It happened again yesterday when I was shopping at Walmart. I done a lot of walking & it felt like shooting pains in the same place in my belly. From my belly button down to my lower stomach. Like stretching / pulling feeling. Almost like my baby was bouncing on a muscle in there with every step. It’s not painful enough to really worry about. I just had a checkup yesterday with my doctor. Me & my baby are doing perfectly fine. I actually spoke with my good friend who is also a RN & she told me it definitely sounds like Braxton Hicks to her. What do you ladies think? Could this be Braxton Hicks?
