Hi. I really need your advice/help. I'm usually never this late. My last period was May 29th-June 2nd. Today is July 5th..I've never had unprotected sex and my boyfriend has never came in me. I'm 19, not on BC, we use condoms and have never had any problems with it. I'm also very careful so please don't call me irresponsible. I've had sore breasts for about 4 days now, this always happens right before my period.. but still NO period. I'm not sure what to think, do I wait? Please comment. Thanks
