Need some advice

Hello everyone I'm very new to this site so I hope what I'm posting is ok :).

basically I have had this bruise on my toe for two months now and it's not shown any signs of improvement. I've definitely not banged it or anything like that if I had I'm sure I'd remember with a bruise like that. I'm hoping yous could give me an opinion on my toe please as I'm very worried incase it's something serious . Thanks x
