DONT IGNORE

Danielle
Hey girls im 18 and have had my periods since the last time i had intercourse which was may 13th every singlemonth meaning june july and august i have had had my periods, i took a home pregnancy test and it came back negative which if i was pregnant i would be 3 months now, anwyays i also took a blood test at planned parenthood and came back negative, my friends kind of scared me telling me that i could still be pregnant???
 Is that true should i still be worried? Can blood test be wrong my boons hurt but i think thats because i been squeezing them everyday for a week now! Just to check is theyre sore.. i know ridiculous right? And ive been going on YouTube looking at all these stories that women didnt know they were pregnant because they had their period which made me very nervous too Anwyays it would be really helpful if u guys could answer my questions thanks god bless
