Is the secret out?

The day of the big bowling party half my secret was revealed. By that I mean my sister Mandie put a couple things together and found out we were trying to conceive. I tried to wiggle my way out of it but I am not a very good lier. Apparently it all started on Christmas Eve. Mandie used the master bedroom bathroom and discovered my boxes of prenatal pill samples the doc gave me. I got rid of our positive pregnancy tests, but missed that little detail. Then while at Dave and Melissa's house, my uncle Dave kept asking over and over again if I was pregnant. The reason he was asking was because an Aunt of mine Margy, is knitting a blanket. Every time she is knitting, someone is pregnant. Mandie notice the look on my face and put the two together. The funny thing is that she really doesn't know everything. She only thinks that we are trying, not that we have already succeeded. Why are we keeping this all a secret? Well.. Jason and I said from the beginning we wanted to try and keep it to ourselves until after our first appt. This way no one can jinks us by saying "it's twins". It really has been fun too.
