Babyplease - yay, PUPO with twinnies!!! Great that that you have some frosties aswell, sounds like you have some lovely little embies there hun. Lots of good sticky vibes for you . The swab tests for strep B think, if your positive you have to have antib's administered during labour.
I had an OB appt yesterday, all going ok. She is thinking they might induce me early due to bubs big size, she wont give me any dates yet, but possibly around 10 days before EDD , which will be good, she said she will talk to me about it more at my next visit next week.
