Hi Claireylou, try not to worry, everything changes at this time in your life and you will probably have to get used to a 'new normal' where you expect the unexpected. Anything can happen - heavier periods, lighter periods, various colours of bleed, clotting, weird stringy clots, shorter cycles, longer cycles, bleeds lasting 10 days or more (my longest has been 20 something). Your periods might just stop all together or this could be the first stage of perimenopause (think I linked to the STRAW information earlier on). If you're panicking about anything, just do a search on here and you're pretty much guaranteed to find someone who has been through the same thing. Light periods with a lengthening cycle do sound a better option than heavy, flooding periods which run into each other if that's any consolation at all.
