Tmi question. Please respond.

Ashley • Met my husband 3 years ago. Married Nov 2013. We have one son (age 2). TTC with baby #2!!!!
Ok, so usually my periods are heavy and last anywhere from 6-7 days. Well this month af came and was very heavy the 1st day (bright red) and the second was a mrs flow (darker red) and today, 3rd day I'm spotting very little. Almost completely stopped...well just some brownish color discharge. Last week I had horrible cramps (still have cramps) bloated, bad headaches, extra tired, moody, extra hungry, and sore boobs so I figuredy period this month would be horrible but nope. 
Has anyone ever had this happen before? What was the outcome? Is there any reason for this month to be outta wack?!
