I think I've just had a 7 day period, but really it was so light I couldn't use a tampon. It started 42 days after my last period and 2 weeks after I had what I think was ovulation pain (I had a jabbing pain where I think my left ovary is and get this in some cycles). But was it just spotting if it was so light?
I've been in peri for a few years now and everything is very unpredictable!
