I have 2 boys from my 1st marriage that my parents helped me through, after my divorce was final I be came pregnant with a wonderful man I was dating, my our daughter was born he lost his job about the same time and we decided to get married a year later. My parents were not happy about my daughter and it was a hard fought battle to win back trust. The story goes on that my parents have financially helped us off and on while my husband went to school to get a degree and hopefully a better job. 4 years later he just found a temp job, but we are struggling financially. I am terrified to tell my parents that we are expecting. This was not planned and we were taking precautions to prevent. So how can I soften the blow and lessen my stress level?

Why do you need to worry about what they think? Is it because you need them to support you financially?

It is not about what they think it is the over all reaction that will have a trickle down affect with the rest of my family. My parents have given me support when I have needed it and yes I feel a bit obligated to them. They are very supportive over all but, their way is the right way I always feel like I am letting them down. I know in the end things will be fine... I just don't relish having to tell them. That's all. It has never been easy to tell them with any of my pregnancies even when times were not ruff. They just don't react well to "good" news.

Well waiting is not going to change it, and better you tell them than they hear it from someone else or start seeing it.

You just tell them, you can explain that you were taking precautions and it still happened.
The best way to lower stress, tell them NOW, and stop waiting

Birth control is basically useless unless it's the pill, patch, or IUD. So if that topic comes up, I would be prepared by saying you have since changed to one of those. Yes, you can get pregnant on them, but the chances are well below 1%. Other methods are much, much higher.
I would also tell them that you don't want any financial help. If they insist over and over, take it. But at least give them the courtesy of not feeling obligated.

Just tell them they can be mad but if they really love you thell be happy for u and start by saying mom dad will you really love through every thing or something to that extent
