Hello ladies! I have a bit of a concern and question. 
I have tiny lumps on my breasts, and I'm not sure if it's the pregnancy. I've never noticed them before. Their obviously a little sore from being pregnant. But, my first OB appointment isn't until the 18th. So I'm just trying to find out. Thank you.
