Uncertain???

I am well aware of what Braxton hicks are, I've been having them since I was like 25 or so weeks but within the past 4 days i have been having cramps in my lower belly. Definitely like period cramps. Could those be contractions? I've been taking Evening primrose oil and drinking raspberry leaf tea since Thursday as well as having sex with my husband and walking a lot more.. just wondering if cramps are contractions or if they're just cramps.. help me!! Thank you!
