36 weeks 2 days over here. So in the shower i felt like i had a bunch of discharge so i checked down there and some mucus-y looking stuff came out. There wasn't any blood with it just looked like a giant bugger that came from my vagina. I thought i noticed some mucus-y discharge earlier today but i wasn't sure. Is this my mucus plug? And if so, even though there was no blood with it, could that mean labor is near?? First time mom here.
