40 weeks 3 days

So today i am officially 40 weeks 3 days and this little boy still doesn’t seem to be coming out anytime soon. I had a membrane sweep on Monday, with a few contractions and cramps that night, then nothing. Yesterday i had ONE contraction while walking then nothing... this morning i woke up with a sharp pain in my pelvis area almost like a pain if you were constipated and we’re trying too hard to squeeze. Then i cooked breakfast for my first born and i and did some laundry. Then i went to use the bathroom, and this came out! I’ve been losing (what i think, never lost it with my first so I’m not sure) tiny pieces of my mucus plug for about 3 weeks now. But since the membrane sweep there’s been more. Could this be it? Could i actually be going into labor soon??? I have no idea what it’s like to go into labor on my own, with my first i had to be induced soo i don’t really know what to expect.
