So being the hypochondriac that I am I'm reaching out for advice. I'm a day late on my period and I'm on birth control (for about a year now) the day before my last period started I did have intercourse and he did ejactulated inside me-- also, my period was two days early before I started my placebo pills. I have the feeling like I'm about to start it and I took a HPT a couple days ago and it came out negative... Am I just freaking out or should I be concerned?
