Two periods last month and this month I’m 9 days late

Hi guys!

Just wondering if anyone ever experienced this before. I’m always on a 28days cycle however last month I had my period then 10 days later I bled for 3 days (I put it down to a uti) however this month I’m 9 days late. Did the deed with my SO last month, he works away a lot so not often, but now I’m confused and I don’t want to get my hopes up, but has anyone ever had this then to find out they are pregnant?
