Braxton Hicks at 26 weeks and 3 days?

For the last 4 days I've been experiencing uncomfortable mild cramping on and off at random times, Babies movements haven't changed and she's very active so I'm not really worried at the moment just uncomfortable. This is my second pregnancy and I've had no problems but it's been over 3 years since I had my little boy, I've completely forgotten what the braxton hicks felt like. Could I be experiencing them or is it just really bad round ligament pain due to baby having a growth spurt at this stage
