36 weeks today

Sorry for the rant, but today I have been very tired and sluggish. The cramps I been getting in my legs and lower back are annoying and its been every hour. Stomach has been very hard sort of like a basketball. I been trying to determine when to go to the hospital. I dont feel right at all, I also took a hot bath to see if it would subside but it hasnt subsided any. What do you guys suggest? Should I just go to the L &D just to make sure im alright or give it time. Sorry for the long post. 😔
