Hi Shay,
The blood numbers, MCV, MCH, MCHC, and RBC don't indicate any type of thalassemia, so it probably is IDA. It's best if iron can be corrected through an iron rich diet, but sometimes supplements are needed. One thing that helps with diet is to take foods rich in vitamin C along with veg sources of iron, as the C will aid iron absorption. As far as supplements, if you have trouble taking them due to stomach discomfort, I have been told that the product called Spatone (iron water) is easier on the stomach.
