I am not certain if this is a real post or not, but just in case it is. Please do not order meds over the internet. I am assuming that is what you are considering as no Dr. would prescribe such drugs to a 16 year old. Ordering these on line comes with far to many risks...it may not be what you think it is. Also, taking these drugs without a Dr. supervision can cause long term problems such as overstimulation of your ovaries.
I agree, at 16, you are far too young for a baby. Your body isn't ready to handle that type of stress, and you're still such a child yourself. I've never heard of a doctor prescribing fertility medications to anyone under the age of 18, rarely if someone isn't in a long-term committed relationship, and definitely not if they aren't stable enough to raise a child. Babies only stay babies for a very short time. Are you really ready to put a child in Kindergarten before you're even old enough to legally drink? Please check out your local community center for someone who is experienced in teen mothering, and spend a day with them. I'm sure you will change your mind.
At 16, you really shouldn't be trying to get pregnant. I'm not sure your reasons but your body is still developing and I'm assuming you are still in school. Raising a baby is hard and takes alot of money. Make sure you have everything planned out before starting a family. Can you pay rent, do you have any savings or a good job? These are very important to raising a happy, healthy child. I wouldn't think fertility drugs would be safe for someone your age either. Please check with your doctor before trying anything. I wish you all the best.
