I am currently 17 years old. About 11 months ago I had an abortion. Now I feel I am mature enough to have a child as I work and go to school full time and am in a full stable relationship and am on my own. 
My boyfriend and I have been trying for several months, and I am getting all of the symptoms of pregnancy that I had before, by the same man. 
Nausea; lower back pain; frequent urination; eating more than I usually would; ect.

On April 27th 2012, I started to bleed slightly from my vagina. No like a normal period at all. I didn't need to worry about a tampon or anything. I didn't get any cramping and only a little blood came out when I went pee. 
On the 29th of April, I started to get severe cramping that would come and go for most of the day, and slightly heavier bleeding, but nothing like my normal period. I would only have to change my tampon every 8 hours and it still would not be "full"
About a week before I started my "period" I have taken a pregnancy text at a local clinic and it had turned up negative.

On May 25th 2012 the same thing that had happened on the 27th of April is happening. I started bleeding very very lightly and only saw blood when I went to the bathroom. I woke up the morning of May 26th with severe cramps but not really any bleeding. Later in the morning I noticed I was bleeding a little bit heavier. But I do not have cramps at all, and that it not normal for me. 
This didn't happen at anytime throughout my first pregnancy in which I was 4 months along before the termination.

I am really just wondering if I am able to still able to get pregnant after the abortion, or this is spotting and I should take another pregnancy test? Or is my mind playing a trick on my body because I want a child so badly?
