@babymomma1215, thank you!

@lucieelledge, it's the hormones going crazy I think

I'm 12 weeks and I have the same thing and have had it since about 8 weeks

I get more milk on my left than my right. it's common

@ashleywilkerson, I think it's my breast filling

@babymomma1215, it hasnt but that's what I think it is. My milk coming in. It's just weird that it's only on my left side

Had your milk supply already started coming in? could be emgorged

Yeah that's what mine felt like to, literally like a knife. It hurt so bad, I wouldn't believe it was just heartburn! Tylenol helped the pain a little, but Zantac did nothing for me. I went to my doctor again and they still said heartburn...but I was still concerned about it because it didn't feel like heartburn at all to me.

It doesn't feel like heartburn. But it's more like stabbing in my breast @ashleywilkerson

I had this earlier in my pregnancy and went in to get it checked out, but my doctor said it was just heartburn (weirdest heartburn I've ever felt) and told me to take Tylenol or Zantac. But I would definitely get it checked out if it's any concern for you!
