Please help ha

Im 18, I started my period at 11 and it used to be regular periods when I just began it used to last a week now my period last 3 days, yet it has been soo irregualr for past 3 years now, I thought perhaps it could be down to my weight i lost alot of a weight at a steady pase but yet no change. I go for 6 months without a period and then I have a period for another 3-6 months then I stop again, discharge happens but yet no period, I get moody like I would be when im about to come on my period but I don't. Im not too sure what is going on... I

Hi Kelly, when I was your age my cycle was like that, you probably should go to a gyn and have tests done. It's best to figure stuff like that now rather when you decide to start a family.
Good luck,
