Delayed for a day - Means Pregnant

Hello Me and my husband is trying to get a baby since a few months ago and unfortunately the past 2 months were on the wrong timing as i am travelling a lot overseas. Then last month, we did 5 days before ovulation and 2 days before my ovulation. My cycle is always 28 days sometime earlier but cannot be missed on the 28th day itself. All PMS and pregnancy symptoms already felt but this month is different. My breast is not as tender as last month but swollen and heavy, then i have sensitivity in smelling, bloating and fatigue every night this past few nights. Until, 2 days ago i thought my period is coming but i saw spot then i thought it will continue, then yesterday where i supposedly expecting my mens also got one spot only. Last night i had a nightmare and im having an abdominal pain when i woke up. Till now no sign. Do you think im pregnant?
