The first thing is that i am irregular and my cylcle is around 28 to 36 days, and im guessing my luthreal phase is 14 days. My last 3 periods where about half the blood i would normaly have. The last abnormal period being on May 10th wich lasted 6 days but very light stoping halfway during the period and starting again. then the next one was June 14th also light stoping in the middle and resarting the same with on July 16 wich started out brownish red. Im normally very heavy, all the time, eversince i started at 16 and im now 25. This last period on August 16 only lasted 5 days and nothing for a whloe day on the 3rd (just like the periods before) they all have small amounts of blood clots too.

My fiance and I had intercourse on these days(sory to be graphic but only pree-cum, no condums)
5/18
5/28
6/30
7/28
8/6

I keept track in case i needed dates and information, i just learned about luthreal phases a little bit ago. My breast have also been sore now for 2 and a half weeks and slightly sick somedays to smells.
Is this just a normal thing with arragular periods or could it be more.
