In brief: Warfarin
Warfarin is a drug you shouldn't be using during pregnancy.
Heparin is safer because it doesn't cross the placenta and affect the fetus. But why do you need these anticoagulants? That cause may increase the risks of pregnancy and put you into a high risk group. Talk to your doctor.

In brief: Yes
You'll need to switch back to Heparin in pregnancy or (lovenox).
You don't give the reason for your anticoagulant so either a blood disorder, heart arrhythmia, artificial valve, or thrombo-embolic event (etc) will make you high risk in pregnancy. You will need an experienced OB or mfm specialist to monitor your levels, infant, & carefully plan your delivery. Take care.
