Could this be pregnancy? Please answer! I involve relief!?

I am 22 years old and I am on the pill (since February) and I never miss a pill or help yourself to it late. My boyfriend and I use condoms most of the time, but if we don't, he does not ejaculate inside me.
My breasts usually start hurting roughly speaking 2 weeks before my spell starts. I got a ordinary period finishing month (12/18), but my breasts never stopped hurting (they have be hurting ever since 2 weeks before my second period). I am due to get my time next Tuesday (01/15), however I bled for a moment bit after sex 3 nights ago (01/05). It be only in that when I wiped and it go away after 3 wipes. 2 night ago I started bleeding again (very light) and I still am. The bleeding is getting a little heavier (enough for a panty liner). It started bad as being brown, but very soon it is starting to get redder. I own passed a few blood clots. I am also having some cramping as if I have/am only about to receive my period.
Does this nouns like implantation bleeding? Could something else be going on?
Thanks. It sounds resembling you keep exceptionally good documentation! That is a good entry. Are your cycles normal? Meaning do they come a programmed every month? If they do and it is very out of the routine for you to be starting this soon then I would budge ahead and make an appt. near you OB. Tell them exactly what you said above. Good luck!
Contact your doctor's office. He/she will know how to help you. I hope it is nought serious.
