is it true that raising your heart rate over 140bpm when in early stages of pregnancy/pregnancy cause birth defects due to decreased blood to fetus?

No: That used to be a misnomer, but has since been proved false. Recent studies and statements by the american college of ob/gyn have stated that women in otherwise good health can and should get their heart rates elevated in pregnancy through moderate exercise. The key is to stay super hydrated. Exercise is great in pregnancy.
