hello im 15, ill be 16 on august 9th. i am extremely worried right now because the last time i got my period was June 14th until June 20th. Me and my boyfriend frequently do have sex but ALWAYS use a condom and it is always put on correctly. Today is July 19th and i have still not got my period. I dont know if i am overreacting or not about this but i need some reassurance. Does anyone think im pregnant or could it just be late due to stress or an irregular diet? because i have had both of those lately as well. My period is not ever on a completely set schedule but this is worrying me a lot.
