Oo, normal yan sa 34 weeks, those are Braxton-Hicks contractions, parang practice contractions lang ng katawan mo before the real thing, kaya don't worry! Pero since parang dumadalas na talaga siya lalo na pag nagbabago ka ng position, mas better kung i-check mo na with your OB just to be sure everything's okay, especially pag may sakit or unusual discharge na kasama.
