I was on depo for 4 years after having my 5 yr old son. I got my last injection October 2005. My period returned and is normally on time and the exact 4 days as it was before I had my son. Well, in May me and a friend "hooked" up spontaneously and yea I must admit, unprotected twice and the second time he didn't completely pull out in time. I didn't realize until after the smoke had settled that it was during my "fertile" time of the month. None the less my period came in May but it was late and unusual like lighter,not my usual flow. Then June and July it was late again and the same, a lighter flow, my first day was like my third would be. Any ways my period should have come on July 30 but it has not come yet. I know it's only the first of August but for a person that period is normally usual this disturbs me. I have heard of people having "vaginal bleeding" during pregnacy and I also talked to a lady that bled during her entire pregnancy, and didn't find out she was pregnant until she was almost 4 months. Her doctor told her it could have been from her being on depo for so long. At any rate is there anyone that has insight, I'm afraid to take a pregnancy test, I don't believe it's stress. What do you think?????????????
