I’ve had a swollen armpit for a few weeks now. I have a GP appointment tomorrow but am sat worrying what it might be. I can’t feel any lump I don’t think, just that it’s swollen and doesn’t seem to go down. I also now can’t remember if I experienced this before or after I found out I was pregnant. My mum had breast cancer in her 60’s - I’m 30 and 13 weeks pregnant. Has anyone else experienced this?
