Hi, i last had protected sex on the 27th of may, from the 8th of june to the 19th, i had experienced nausea, stomach pains and lack of appetite. duri?

Protected sex: So I'm hopeful that you're feeling fine again since 19th? By protected sex, I assume you mean you/he used a condom, since you didn't list use of any hormonal birth control pills. Problem w/condoms is that they're not 100% effective, although they're still recommended to lower risk of both pregnancy & sexually transmitted infections. Take pregnancy test if your period is late.
