I usually start my period on the 29th, but this month I started on the 23rd, exactly one week before my period is due. Well, I thought I started. It was only a light pink spotting during the mornings and when I wiped. The only time I bled what seemed like a normal flow was during sex with my partner. I've had a few cramps in my lower abdomen and my body has been sore, but I didn't think anything of it. It's the 30th and I still haven't gotten my period. I haven't been on birth control in quite a while and my partner and I always have unprotected sex. The tricky part though is that he's been told and tested for quite a while that he's unable to have children. He even tried with his ex wife and nothing happened. So I'm just kind of confused.
