Pregnancy brings about many hormonal changes. These are important as they help to support the Pregnancy and allow the fetus to thrive and grow. But at the same time can cause mood swings. On a minor level expecting moms may find themselves upset over small issues, may even cry a little over trivial things or snap at others in tiny matters. However if it affects your day to day life, if you find yourself not able to enjoy yourself or find something to smile about or feel detached from everyone or are feeling negative and low all the time then it is time to seek some help. Do remember it's ok to ask for help as what you are going thru is normal and not in your control hence support is vital. These moods can continue into the post partum period as well and hence having your family understand what you are going thru is vital. Sonali's Desk.
