Can constipation make BH contractions stronger?

I've noticed a big increase in contractions the past few days. They've been very intermittent but they went from like 6 a day tops to at least a few every hour or two throughout the day. Still not really a pattern though. However overnight and this morning they seem more frequent and stronger. I've been constipated for a few days about the same time they started getting more frequent, and when i have them it really feels like I need to have a BM but it's like a bad period cramp all in one. I'm only 33 weeks so it seems way too early to be going into actual labor.
