Hi. I’ve looked at your pic and although mine was a lot smaller it does look like a similar thing. Just keep an eye on it that it doesn’t get any bigger. And don’t forget you have the emergency number on the red card should you need to call if you’re worried. Mine took about 2 weeks before I noticed it going down but everyone is different. I still have yellow colored bruises over my left breast too. I’m sure it’ll sort itself out but yes still try and call again Tuesday. Hope you’re well anyway besides the bruise. xx
