Could I be pregnant ? UPDATE

I’m 2 days late for my usually pretty regular and predictable 3 day period. I’ve been having mild cramps which keeps making me think my period is coming soon. I have the sorest nipples ever. I’ve been feeling ever so sleepy and low energy all the time. Could these be symptoms of early pregnancy?

Me and my boyfriend have been having unprotected sex.

This is the latest my period has ever been, so when is too soon to take the test.

I keep pushing it as I don’t want to get too hopeful!

UPDATE

So I followed all your advice and me and my boyfriend rushed to get a pregnancy test and I have taken two and both were positive!! Aahhh I can’t believe it, we are so happy! Off to the doctors tomorrow to book the blood test to hopefully confirm it ahh
