I wasn't going to post this because I didn't feel a cause for concern, but now I'm curious...and getting a teensy bit concerned.

Yesterday morning when using the restroom before my shower, I wiped and saw just a small little bit of pink. Okay, well I know it's normal at this stage for various reasons, but to ease my mind I called L&D at my hospital and they said baby likely is getting into position and my cervix may be dilating a bit getting ready for birth. I told her I was 7 months pregnant and she said it was normal, even this early. They also said only come in if I start bleeding. Well, my son was kicking all day and has been just fine. I went to the restroom just now and saw another tiny pink spot on my panty liner (I wear them regularly since I've gotten pregnant because of increase of discharge). It's just one tiny spot. I even checked to see if their is more pink inside and there is not. But this time, I'm having a little achiness in my back (but again, I am 7 months pregnant and with my belly growing I figured it's normal) So, one tiny spot and a tiny bit of uncomfortable back pain. Anyone else who just hit their 3rd trimester dealing with this? I shouldn't worry, right?
