The recommended contraceptive method and follow-up period after a complete hydatidiform mole evacuation before attempting conception is:

• A Combined oral contraceptive pill for 6 months followed by serum beta-hCG normalisation
• B Any reliable contraception for 12 months with monthly beta-hCG monitoring
• C Barrier contraception for 6 months; conception allowed once beta-hCG normalises ✓
• D No contraception restriction once beta-hCG is undetectable for 2 consecutive weeks

Explanation

After complete molar pregnancy, conception should be deferred until beta-hCG has normalised (two undetectable levels) and for an additional period allowing adequate surveillance. Barrier methods are preferred during surveillance as they avoid the theoretical concern that OCP might sustain trophoblastic activity (though evidence is now more reassuring for OCP use once levels are falling). Current RCOG guidelines advise deferring conception for 6 months following uterine evacuation provided beta-hCG is normal; pregnancy does not worsen prognosis once surveillance is complete.
