Hi, i need opinion from u guys. I'm 18 days late and it's unusual because my period is usually spot on with the predicted date on period calendar app. For the past 14 months, I'm only late twice by 7 days. And those times were the earlier months I was married, so I blamed it on hormonal change. Now that I’m more than a week late, I have been testing with UPT, probably have used 5-6 sticks already. I took a test last week, got a negative. Then I tested again after 7 days. Still negative. It’s driving me crazy. Should I go get a scan or a blood test? Or should I wait any longer? We are very hopeful to get preggy 
