Should I give up hope?

I’m currently on honeymoon with my husband, we’re on a cruise and get back on Thursday evening.

My period was 5 days late and I’d convinced myself I was pregnant, I was showing all early signs, fatigue, bloating, peeing all the time etc then this morning BOOM bleeding. To me it seems quite heavy but I could be over thinking it, there’s mild cramping but not as extreme as regular period pain.

Should I give up thinking I’m pregnant and accept that I’m just incredibly late this month or is there still a chance I could be pregnant? To add I’m never normally late so to be 5 days late I was sure I was pregnant :(.
