What is this??!?!

Hey ladies, I’m 20 weeks pp today. This past week my incision as been itchier than usual and bothering me. So I looked to see what the issue was and find this lump. It’s kind of firm and really itchy, a little red also... I feel like it could been an ingrown hair or infection. Anyone what this before? What do y’all think? Should I be worried? Thanks in advance.

Update:

Thanks so much for the responses. I popped its own and healed. I think it was an infected hair follicle or pimple like.
