Hi all,

bit of cry for help, I'm currently a very anxious 27 weeks pregnant lady. 
 

story- I found out I was pregnant beginning of June (so happy) about a week later I found a lump in my left armpit, very high up! I waited a few weeks see if it went but it didn't. Cut to the chase went to GP got referred to breast clinc,  had the usual check and ultrasound preformed on armpit. (Very quick) got told nothing to worry about and headed back to the consultants room, told basically it was just a node nothing unusual looking and could be because of the vaccine. However I had the vaccine back in March 25th so this means 4 months on still ther and to now 8 months on. 
was told could be there while, but that just doesn't sit right with me and makes me so anxious I'm constantly checking it, still there today all though I just admit harder to find and not as promenante, I also feel more tenderness there now which I guess steams my anxiety. 
mother symptoms are that sometimes my armpit feel like it's stinging. 
 

ahh as you probably can tell I'm so anxious, I'm not coping the best and I just don't know what to do! I'm just so worried that something has been missed or it's developed or something. 
 

please help
