3 positives!

It has been a really long time since I was on. I am engaged and living with my fiance. I've had 3 positive pregnancy tests, and I'm thinking I'm about a month along. I plan on going to planned parenthood sometime next week. I'm a little nervous. I haven't gotten my period yet, but with three positive tests and only 3 days to go, I'm thinking the chances of me being pregnant is pretty high. I'm worried about my ability to be a good mom.
