Hi I'm 18 yrs old an this happened about maybe a week or two ago but I really could use opinions of others on this,

Well, I got my period an it was very heavy an had clots in it, so I was kind of worried but I thought maybe since I did not have my period for four years because of the depo I was okay because it was back on track since oct. 2012 so I was getting it on time every 28 of every months so when I got my period it was very heavy an had clots in dec. 2012 an me an my fiancé been having sex every time I got my period an after because we've been tryn to conceive, but we had sex before my period an I knew I was getting it on the 28th an when we had sex I started to have my period on the 25th which worried me ever more, well the fourth or fifth day of my period I started to get headaches, dizziness, really tired, an nauseous, well my period lasted for 11 day it went from heavey, to normal, then very light pink an brown, so every since I've been worried an looking up different things but nothing seems to have anything that I'm dealing with, so I just wanted others to give me their opinions other than stupid Google.

This is quite normal considering the length of time you were on depo.
