If you’re still under midwives they’ll be able to check. If not health visitor or triage if there’s any other symptoms like fever etc x

That doesn’t look right. Definitely get it checked. Have you been keeping it clean with water and cotton balls round the edge?
Yes that doesnt look right to me. Ring your health visitor and I'd bathe it with cooled boiled water and let some fresh air to it.
