Hello.


I'll start that my periods are not perfectly regular, sometimes (rarely) I miss them for one month (It happens usually once or twice per year).
I had sex on the last days of my las period, it was about 17th Feb, after 6 days I had brown discharge that lasted two days. It was like normal discharge just brownish. I thought this is ovulation bleeding, because it was 14th day of my cycle or so, though I never experienced that before.
Now my expected period is late for 2-3 days, and I would not worry, but I don't feel any symptoms, no tender breasts, mood swings, nothing. I feel like normal day. What could be the cause? Could it be pregnancy? (My boyfriend did not finished in me 100%).
By the way after my last period I totally changed my routine, I started working at nights, big sleep and diet changes. Could this be a reson of my late period?
I am 21yo
Not on any medicaments
Thank you!

First of course 2 or 3 days is not really considered late. A late, or even a missed period can be caused by changes in your routine, diet, stress and many other things.

There is plenty of sperm in the early fluids, so your boyfriend not finishing does not stop pregnancy.

So at this point, it is just unknown. You need to wait about 2 weeks, and if no period then, test using first urine of the day.
