I am 5 weeks today and have my appointment next week with my doctor. I have a family wedding this weekend and all my siblings and dad will actually all be together. My sister's (I have 4 older) have been talking about it for awhile and are very excited to stay together and party. Being the youngest, I've always been known as "the partier" so, if I come up with a lame excuse I'll be called out on being pregnant. my husband and I agreed we don't want to tell anyone until after the appointment.....any ideas on what we could do?!
