It was more than likely caused by the check. You could also be entering an inactive phase called promodal labor. It can last for a while. It is just your body preparing it's self for active labor.
I'm almost 40 weeks and I got checked yesterday. I was cramping on and off the whole day but it got less and less intense as the day went on. I thought it might of started labor too but it didn't :/ just hurts like heck!
Early labour can sadly start and stop /: by the sounds of it that's what you're experiencing.. i had this with my first, all i can say is ignore it until contractions are close together and the pain feels too much, once you hit the next stage it's full blown labour and it won't stop. I had this for a few days with my first then spent a day walking here there and everywhere i had her at 38+6 (: my second was a completely different story, i had him after a sweep at 40+4 good luck!
Ah thank you ladies. How frustrating it is when us mommas are so excited and something like this happens then just vanishes! But baby will come when he's ready (: your comments helped thank you. Fingers crossed that I'll go into labor on my own!!
