Strange A/f - anyone similar experience?

Hey this is my first time posting so bear with me :) Anyhoo I am currently having 28ish day cycles sometimes a day or two difference either side. I have always had 6-7 day long periods and since the birth of my daughter in 3 yrs ago days 2-3 are always very heavy then 4-5 are medium and lightening on day 6 to spotting on day 7. But this month my period arrived early monday morning abt 1am or 12 am before the clocks changed sat night. so had 27/28 day cycle. So mon was light brownish red (sorry tmi!!) and severe cramps i was crippled with pain to point my mum came over and took me to a&e. all they did was give me strong pain med no tests of any kind. Then tues was still light and redish brown still cramps but not as bad, weds was lighter but brown flow still few cramps then yesterday thurs was even lighter brown and had finished by late evening and today fri nothing just starting to get normal discharge. The odd thing is i still feel soooo pre menstrual!!! Sore boobs moody bloated cramps tired irritable.
Anyone similar experience?? Thanx xxxx
