Mixed feeling

I have that exact same feeling when I get to know I am preg. My 1st born is 15yrs old this yr. We been trying for past 10yrs but failed. Just when we thought its better for us this way as son has grown up and we have more time for ourselves, since we are both hitting our 40s, we were caught by surprise with the pregnancy news. We are 17 weeks preg now.. and as much as we are excited, we are also worried cos we have to start all over again after 15yrs, especially at our age now. However, we are def thankful for this little blessing God has given us.
