I need answerss . . .?

I havent had a period since april 17 that was my last period. My boyfriend and I dont use protection, i soon noticed that my boobs have grew large an sore, my nipples are always hard, and huge and dark. I get tired/sleepy all the time and take naps throughout the day. My lower stomach is hard as a rock an it was never like that. On june 18 i began to bleed but was very light an then it quit BUT now i bleed again but its not my normal period because it doesnt bleed as much as a period, i dont understand if its normal, my bf's tia/mom say its normal an i been reading that it was to but im not sure i need advice from ppl that have been preg an this has happened to them
