Really sore boobs

Hi, thanks for taking the time to look at this.

I am 14 weeks pg with my 3rd. I initially get sore boobs when first pregnant that has lasted up until about 9/10 weeks. I know every pregnancy is different..this one certainly is! I did have tingly nipples as an early sign, but then they were ok. In the past week my boobs have become really sore with shooting pain and my nipples are sensitive. My dh said that my nipples have turned purple! I know they are hot too.

I suppose I want to know if this is normal, but also is it possible to develop mastitis/blocked ducts this early on? Anything I can do to help ease the uncomfortableness of it all?

I suppose it all goes with the completely different symptoms of this pregnancy...ongoing m/s, tiredness, huge tummy!

TIA
