I had my period on the 8th of may and it lasted 4days. But for some reason it has been different to the last period I've had. I th
En had a little bleeding 2 weeks before I was due on again. Then the 5th of may come and I come on but it was very different it was lighter and shorter than my normal periods. I have been getting signs such as; period pains like cramps, feeling sick, tiredness all the time, eating different things I don't normally eat, constipation and my smell of foods and drink and I always need to go to the toilet a lot more than I used to. I am very confused :/ suggestions

I have been in this position, I know what its like. I was 11 when I started my period and now I'm 14. I have some experience and I hope this will help you.
Don't be worried. Most people have their periods every month, yes? And it lasts for about 3-7 days. A few months ago, I was feeling a bit like you. I was getting worried and I was starting to think if I was pregnant because it has been 6 weeks since my last period. I was worried. But then I was OK because my period came back on. Periods are different, some are very heavy and some are very light, but its all normal, its nothing to be worried about. Your eating different foods that you don't normally eat? That's just another normal part of growing up, its showing you that your turning into a stronger young adult and its good to try new things. Make sure you get as much sleep as possible! On weekends I wake up at about half 10 in the morning because I'm so tired, that is just another part of growing up. I never actually know when I'm due but I can see I'm due about this week or maybe next week. This week being week 4 since I last been on my period or I could be a week late (week 5) But this is normal. Your period changes over the months. Pains, cramps and feeling sick, we all go through that and I'm afraid its just mother nature at her spells again! Going to the toilet, this could be a sign of you being due maybe next week or the week after, or your just drinking a lot :) Just remember some periods come early and some take there time but they will eventually come and go. I only have 3 years experience on this so you might want to ask maybe some older relatives or your parents for more advice :)

8th of May and then 5th of June (not May) right?
With spotting in between?
That is a very normal cycle, with normal mid-cycle spotting.
The fact that it feels 'different' in many ways can be a sign of pregnancy, plain old fluctuations in hormones, menopause, anemia, other illness, or stress.
There is NO way to know until you do tests.
