Is this a warning?

Hi im 35 weeks and this week i have been so tired i cant function. My heartburn has started up and is getting worse and the meds i was perscribed doesnt help. Lil man is a very strong mover and i feel lightening quite often down there. So i guess im wondering if all of this becoming more intense is a sign that labor could be 2-3 weeks away? I know all are common with pregnancy and especially in 3rd trimester but with the increase in intensity it almost feels like somethings off even though its a totally healthy pregnancy.
