Women...Is this normal? Only women would know the answer.?

I've been dating a girl for 6 months...we are happy together, but she just started pill, got sick whith bronchitis, takes cles and is having some women issues...she stressed to the max and says "everything is wrong" and I'm trying to be as loving and supportive as possible...always helping her with things, telling her she's beautuful, etc. i love her more than anything, and even though she's says "believe me, nothing is wrong with u", i can't help but think their is cause it's so new and maybe have some insecurities. Is this normal for girls to act when stressed, sick or starting the pill? Thanks
