Sounds like u may have been having contractions. The period pain are usually the onset of labout but u can get it weeks before u go into labour and usualy causes pain in the back.
Idk if im dialted my drs wont check me until 40 weeks so im clueless.
Are you dilated at all? It may be a sign that things could be moving along for you. If it felt like you had to poo really bad it could be the pressure of babys head pushing down there.....apparently during labour your suppose to push like ur taking the biggest poop ever, hence why lots of women poop the bed during labour.....i dont know what the signs are for labour coming along but if ur water breaks soon then baby is coming lol
Yea it felt like i had to poop bad idk it was weird. Im 38.4
Not sure....maybe uterus stretching. Braxton hicks are like mini contractions. They usually dont last long very irregular and they hurt like menstrual cramps. How far along are you? If ur worried you should call ur dr and ask.
