Infection near incision site - anyone else?

Hi, I had a lumpectomy almost a month ago and today I noticed a wound site on my breast about 2 or 3 cm from the incision near my nipple. 

it appears to maybe be an infection and had to happen on a long weekend - unable to get hold of the surgical team. Went to ED and I have antibiotics, they took a swab and have set me up to get an ultrasound. I’m scheduled to have a second surgery to remove a further lump/cancerous area and finalise breast conserving surgery this week - Thursday. Has anyone else been in a similar situation at all? I guess as I have a wait to speak to my surgeon on Tuesday, I’m trying to get an idea of whether the surgery may be delayed. Each case is different I know…I guess I’ve been waiting and hoped that it would all still go ahead
