I'm seventeen and have been having sex with my current partner for three months. I've been on birth control for a year but sometimes I'll forget a pill until the next day. Also, I was just switched from Yaz to Loestrin. We don't always pull out or use other forms of birth control. Lately, I've been having:
Cramps
Nausea, no throwing up
Stomach pains, not like cramps
Brown 'spotting' two weeks before period
And my last period was four days and late, usually seven and regular.
Just curious as to if this could be a pregnancy or something else.
