What are the effective methods of contraception?

Patient's question:

I got married this year, and I feel like I'm still a child. I want to wait two more years before getting pregnant, so I need to breastfeed right now. Here, I want to consult with my friends in the medical field about effective breastfeeding methods. If anyone is familiar with these techniques, please help me understand. Thank you

Doctor's answer:

If you are not planning to get pregnant for the time being, you can still decide on using condoms or suggest taking short-term oral contraceptives, which are relatively safe and have no significant side effects. Therefore, you should take good care of your body, observe carefully for a period of time, and avoid extremely cold foods. Pay attention to eating small meals frequently, staying warm, and hydrating. If you use improper breastfeeding methods, it may lead to an unexpected pregnancy. Be cautious and safe. In summary, this can serve as a reference.
