The only help that can be offered now is that if you end up not being pregnant, get some birth control.
No one here can tell if you are pregnant or not, if you are not experiencing your normal cramping, bloating and other menstral cycle issues, then there is a good chance you are pregnant.
Go to walgreeens and buy a ten dollar home pregnancy test. If it is negative, go get bc if it is positive, do whatever you feel is the right thing to do.
If you do decide to keep the baby, get a 4 dollar bottle of folic acid and take one every day until you can get a prescribed prenatal.
