Answer 1

Besides the whole body preparation for pregnancy explained in Dafuzz’s excellent comment, another reason for weight fluctuation is that some parts of the cycle have high level of hormones that make you retain water.
Basically:

* Period: estrogen and progesterone at their lowest, uterine lining is shed.
* After period and before ovulation: estrogen rises, making uterine lining grow and signaling the brain to produce luteinizing hormone (responsible for releasing the egg). **Estrogen also suppresses your appetite.**
* Right after ovulation: estrogen drops.
* After ovulation: progesterone rises, stopping the lining growth and helping support pregnancy. **It also stimulates your appetite AND makes the body retain water.** If no fertilization happens, progesterone eventually drops, triggering a period.
