The longer you go without telling them, the worse the outcome. You made some decisions that put you here. Time to own up. If you’re going to keep the baby, you will need lots of help. You’re parents can help you get the medical advice, and treatments you need while carrying the baby. There are many things that need to be monitored, to ensure the health of the baby and yourself. And, at 16 you’re going to need more help than a boyfriend. That’s just a fact.
In life, there are times when we need to lean on others. It’s not a bad thing. It’s normal. If your parents might be mad, that tells me that at least they care about you. That’s more than many have. Not involving the parents would be making more bad moves. If you care about your parents, and the baby, you will alert them of this situation immediately. Being a Mom is the most important job on the planet. Part of that job, is being responsible.
I can’t imagine how stressful this must be. I wish you the best of luck. We are all human, and therefore imperfect. But you can make some better decisions going forward.
Peace n love.
