Had my 33 week appointment this morning. Baby A is head down and putting pressure on my cervix, which in turn is making it thin out. As a precaution, OB wrote me out of work and put me on bedrest. She said that with babies head putting pressure down there and the heavyness of the uterus with twins (I measured at 41 weeks today) that the last thing we need is gravity working against us.
This will be interesting with a toddler!
