Periods

Chloe • I am 2O years old, in a relationship and currently trying for my first baby. I would love to become a mum.
I'm just wondering if any of you have really irregular cycles and sometimes bleed for more than 1 week. This month I have gone from light bleeding, to really heavy, back to really light again and still bleeding after 2 weeks. I'm also having light cramps and blood clots, and servere stomach pains a few days ago. I'm just wondering if anyone has had the same and if so what the problem could be.. thankyou.
