I had a tubal almost 2 years ago, since then. I've had a regular period every month. This January I had it for a whole week, exactly 2 weeks later in February I for it again for an entire week. I didn't get one for march until this past Friday, I went 45 days without a period and only bled for a day and a half. Is it premenopause, or even possibly pregnancy? Anyone please help!
