My book Pregnancy Day By Day says it’s time to purchase bigger bras, I don’t see such a need unfortunately! Apart from checking whether my breasts were bigger, I spent the last week of this risky period (5-10 weeks when the risk for birth defects is highest) doing some sightseeing, socializing and chilling.
What is happening this week?
