Moderate exercise has been found to be beneficial for pregnant women. It will not harm the baby or its blood flow. Women who exercise tend to be more healthy and have better pregnancy outcomes in general.
How you feel during exercise is key. As long as you don't feel bad, excessively short of breath, headache, chest pain, dizziness or faintness, then you should be fine.
Your exercise program sounds reasonable and should help you to have an excellent pregnancy. Congratulation!
