well, i had my last period on the 2nd-5th march and was due at the end of the month because i have a 28 day cycle. me and my boyfriend have been having unprotected sex since the 5th march and he has came inside me almost every time. The expected period at the end of the month didnt come, but about the 15th of this month,i started bleeding. which is about 6 weeks after my last period.. it is lighter than my regular periods but not by much.and i get cramps a lot. also for the past couple of weeks my boobs have been achy and have became a lot heavier and fullerm and ive also been getting very tired every couple of hours and drinking a lot more, also very emotional and i have never been late for a period which is why i think i may be pregnant. if anyone can tell me if im pregnant or give me advice as to whats going on it would be much appreciated :-) also can you tell me if its just my body playing tricks on me..
