"i started taking sprintec about 3 weeks ago and my appetite has also gone down - which is a good thing. but the biggest side effect i&#039;ve noticed for myself is that my breasts are very sore.  i was starting to trip out because that was one of my signs of pregnancy with my two children - but after reading the reviews i see that this is happening to other women as well.  i guess i&#039;ll know for sure next week whether i get my period or not. i haven&#039;t had any breakthrough bleeding or anything like that or cramping. i am prone to yeast infections but haven&#039;t gotten one so far.  i hope this doesn&#039;t make it worse for me on that issue, like i&#039;ve read it&#039;s done for a lot of other women."
