Missed period

So I’m on the combined pill and after the first month taken correctly I had a 7 day break for my period and it came on the 4th day. Then the week after on the Saturday I had unprotected sex but I had started taking the pill again that Monday and finished that month. But I’m on my 7 day break and my period hasn’t came yet n it’s the 4th day.

I went to a clinic on the Monday after the unprotected sex on the weekend and asked if I taken the break correctly or if I needed the morning after pill but she said I should be fine although I’m paranoid because I haven’t had any of my usual period symptoms that I normally do? Does certain things affect the period not coming?
