Maybe pregnant?

I’m 17 years old and my boyfriend and I don’t ever use a condom (I know we should be more responsible and careful) I take birth control but I some times miss days by accident. We had sex June 2nd and then I started having some weird symptoms about a week after that, I don’t know if I’m just worrying but my boyfriend definitely thinks I’m pregnant.

My symptoms are...

Lower abdominal cramps

Sore boobs

unusual discharge that I don’t usually have

I’m completely exhausted all the time

My lower back hurts (it usually hurts but more than normal now)

And Nausea

It might be ovulating but I don’t usually notice it like this and I should get my period in about a week.
