Braxton hicks or real labor?

I went to the hospital earlier this week bcz I was having pain in my lower abdomen and low back pain. I was diagnosed with an UTI. I haven't gotten the antibiotics yet, I'm getting them today. This morning at 6:00 I woke up to period like cramps, back aches, feeling the need to vomit and feeling like I have gas. I have not released any toxins or went #2 yet. I went pee this morning and when I did, I felt a sharp pain in my uterus when I released the urine. I have also not been able to throw up, I just have the feeling. I went to lay back down. And it just seemed to hurt more and more. I took a warm bath for 20 minutes and they still haven't went away completely. They're still there just not has painful as earlier. I've tried changing position, still hurting. I've walked around the house a couple of times, still hurting. I'm laying down now trying to time them. But they just seem like there really close. But it's just a constant period cramp. Is there anything I can take to relieve the pain? I drank a cup of water as well. I read online to just ignore them and go about my Daily routine and if they really are contractions, my body will let me know. I'm a first time mom, so I'm new at all this. Could I take Tylenol to help with the pain? Could this be Braxton hicks? Could it be a sign of labor? Or could it be the UTI? I'm gonna go and get my antibiotics today when my pharmacy opens and try one of those pills to see if that could be the cause. I'm used to being up this early so it's not interfering with my sleep. Let me remind you that last night, me and hubby did the nasty. (Don't know any other way to put that). I wasn't having any pain while doing it. But I did feel nauses and a little cramping after. I am also 34 weeks and 5 days. I just need help.
