Oh and I'm 37 weeks tomorrow.
Its probably both your probly spotting from the exam but when they check you it can cause you to lose your plug or start dialating. After my 36 week check I lost my whole plug it had a bit of blood. Then after my last check on teusday I have had lots of mucous every day. Was spotting the first day but not anymore I'm pretty sure its just from me starting to dilate. That's probly whats going on with you.
Yea makes sense ill have to keep an eye on it I've been pretty tired to and kinda nasuated all day.
