help me ! I don't know what's going on with me...

I had this great idea a while ago to skip my period.  Ever since then I've been feeling anxious maybe even close to depression.  First off... I'm on a triphasic packs of pills.  I skipped so that I could spend the weekend with my boyfriend.  We had unprotected sex during that time (should have been my period but.. I skipped.  We had 2 times protected, 2 times in protected.  He never came inside me with the unprotected ones). After that, we didn't have sex until 2 weeks later... also in protected.  3 days after that, I had some light pink to brown discharge.  That lasted a week.  My period was supposed to start the next week.  It kind of did.  After all the weird brown/ pink, it turned red.  The red blood was dark.. then light.. and then suddenly it turned dark brown.  It's been alternating for a day now.  (I've had my period for 4 days.. which is it's length when it comes to using these pills).  What is going on?  I don't want to be pregnant.... but I can't tell.  Is it the hormones from the pills?  Or what's going on?  From the anxiety I've been having emotional breakdowns and I just don't know!  I'm still young (18).. and my parents would kill me if I were pregnant.  Help please 😞
