Pregnancy is not an inexpensive thing, and medical care will be needed all along. If you are a couple and married you should be planning and saving towards that expense if you are planning on children. But the guys who are out there for casual sex and don't use birth control are irresponsible. In most countries the father ends up paying his share in child support once he is proven the father even if it was a one night stand. People need to be sexually responsible and those guys should at least use a condom. It's not failproof, but it's better than no protection at all.

That's not a problem only in Nigeria... However, the medical system is expensive and women dying because they can't afford to get proper prenatal care is horrendous. Or if you have a chronic disease and no access to medical care or medication it can be a death sentence as well. I really wish there was a world wide solution to help all those in need of care. Doctors Without Borders do help but are very limited in numbers.
