Labor or what!?

The whole pregnancy I've been constipated, h till the last two days. I've been to bathroom several times a day, but not loose stools.. shortly after I become nauseous. Today I laid down at one point my legs went numb. I took a nap. Woke up lower back to middle of back is constantly hurting, contractions but not real close. Can't get comfy. Just really feel weird..

32 weeks--

Has anyone has this issue or issues similar ? Went into labor or shortly after went into labor?

Any weird signs and symptoms
