Second period

Hi guys so I had an ectopic pregnancy in May. Middle of May they could see something in my tube that ‘may’ be a baby so they gave me methotrexate, that didn’t work and by the end of my I fell to the floor in agonising pain as my left tube burst, I had a laparoscopy same day. They left my ovary just took the left tube. I was then bleeding for 4 weeks afterwards like a full on period now I’m waiting for my second period but it’s 3 days late, has anyone had problems with their period after surgery?
