Recent surgery and late period? HELP

Carrie 💃
So about 2 months ago I had surgery to have a 9cm cyst removed off my left ovary and as a consequence I had to have my coil removed which I had in for 3 years and I loved it. So I had a period which was pretty average and I'm assuming my body may take a while to get into a regular cycle? But prior to my coil I was pretty regular and now I'm 5 days late and have a lot of pregnancy symptoms. I have taken a test (clear blue) which looks like a very very faint line but since then I've done another which was negative so I think the line is an evap line. I don't feel like I'm going to come on anytime soon so I'm very confused!
