Hi.
Thanks for your query and an elucidate history.
Yes, there has to be a reason for this fluttering feeling and pain in left pelvic area and the feeling of baby moving.
Your history of cancer breast noted, very uncommon at such an younger age.
I would suggest you the following since you have a complicated history for your young age.
Go for
CT scan of the Abdomen to make certain that the cancer has not spread to the ovaries , the cysts of the ovaries can in fact be secondary cancer growth.
This will prove what it is .
This can be
colitis as you are loosing hair, bloated and feeling full.
I would advise in such a case the following:
Take a course of an antibiotic and
metronidazole, activated
charcoal tablets, probiotics and most important the therapeutic dosages of Multivitamins. This may help you symptomatically.
