I can’t tell if it’s labor or not

Aime

I’m a FTM and I’ve read stories and have been told what labor and early labor is supposed to feel like but I’m still not sure if what I’m experiencing is the real deal. I have sex with my boyfriend about 2 hours ago, very simple sex and then I showered in hot water after which I’ve always done. For the past half hour I’ve been experiencing light cramps and then some tightening but nothing I can’t handle. Then in the past 10 minutes or so I’ve had 2 really bad tightening in my stomach that started out as slight cramps and worked it’s way to the strong tightening and then in my lower back but as it got to my back it wasn’t that bad. I can’t tell if these are contractions or Braxton Hicks. Any advice or knowledge would help thank you!!
