I'm gonna start of and say: My period is irregular. My last period was on August 25. Normally my cycle is 36 days or 37. I was suppose to get my period on the 1st of October.. Out of nowhere I got it today, exactly 12dpo.. So from counting from the 25th to today it's only 30 days, exactly a week before my actual period.... I thought maybe it would be implantation bleeding but it's get a little heavier.. Hopefully it stays the same and it doesn't get heavier..
