"i took natazia for 4 months after taking levora/portia for 2 years. my libido went way up, in the first 2 months everything was fine, my period was light, my appetite decreased, and i even lost a little weight. however, in the last 2 months i had bleeding every 2 weeks. i bled in days 10-15 exactly like a heavy/regular period. i began getting chest and facial acne and headaches (which are not normal for me). so after 4 months, i had to switch. the increase in libido was awesome, but it is not so awesome to be &quot;unavailable&quot; for additional days (beyond period) each month."
