No one can tell you what's right or wrong for you. Only you can decide that. You should consider the following though:
-Money. Could you support a child's basic needs?
-Housing. Do you have a stable place to raise a child?
-Bills. Goes along with money.
-Future plans. Do you want to go on to university? Do you have a dream job? Are you planning to stay home with your child (and are you able to do that?) or will you rely on using a nanny/daycare and work instead?
-Relationships. Is your partner ready and willing for a child? Are you hoping to marry some day? If you and your partner split up, are you prepared and okay with being a single parent?
-Emergencies. Goes along with money as well. Do you have a "rainy day" fund you could draw from if there's an emergency?
-Support system. Do you have people you can rely on to help you through your pregnancy and afterward with your child?
-Emotions. Are you trying to replace the child you've lost? Do you feel truly prepared to end your "childhood" and become a mother?
There are other factors to consider as well, but I'll leave you to consider these first. Either way, I wish you the best of luck, and I invite you to stay around and listen to other women as they talk about their pregnancies, babies, and lives with children. Best wishes.
