I went through an unprotected intercourse after the 55th day of my delivery date. Unknowingly my partner started ejaculating but removed it immediately. My first pregnancy was unplanned and happened after 1/2 unprotected intercourse. I want to ensure not to plan a baby again. I'm under multivitamin medication and nothing else apart from that. I haven't had my periods yet. 1. How can I ensure not to get pregnant? 2. Please recommend a safe way to avoid pregnancy and any contraceptive pill after the delivery which is not harmful? 3. When can my periods get started? Can I get a quick reply for this question as it's already more than 39 hours having an unprotected intercourse. Thanks you
