My cycle is 28 days, last period was due on 24th June,  period got delayed and came on 26th. However i did not notice any regular PMS symtoms.  We had inprotected sex around ovulation. I experienced some flow on day 1, later there was hardly any flow in following days. Usually i experience heavy bleeding for 3-4 days.  This time it was just few spots after day 1. I did not experience any bloating prior start of period, however feeling bloated since spotting is over. Also feel tired and exhausted all the time since then. Do not feel like eating. Can i be pregnant.
