Clogged milk ducts ?

Christina • 31 years old, I have a 10 year old son! I’m due July 30th 2019 and I’m having a girl 💖Scheduled C-Section July 23rd

I think my milk ducts are clogging! I get these welds but really reminds me of over sized mosquito bites lol! They take over 1/2 my areoles and come slightly out onto my actual boobs itself! Some of them are line welds that make my nipple completely flat! They don’t hurt, they are not warm touch , they Are just there! They go away after I massage them and run them under warm water! It’s been going on for over a month and my DR said it’s too early for that! To come in when it happens again, But every time I notice them so I can go to the doctors, they go away (of course right) I’ll be 28 weeks on Tuesday and have an appointment than! I hope they are there when I go! Anyone experience this before ?
