Ortho Evra
"started the patch this month, am on 4th day of the patch free week and spent the last few days terrified that i might be pregnant - today I got my 'period'  aka BC withdrawal bleeding but have been nauseous all night. so, still not sure where I stand on the pregnancy thing. have also noticed:
sore breasts
weight gain of around 5kg despite no increase in appetite and sometimes even eating less than usual (not fun since I'm already overweight to start with) 
strange dry itchy rash on my lower inner thighs
some vaginal dryness
overall I don't have much confidence in this... even if I'm not pregnant it's scary to see the edges peeling off or a regular shower loosening the adhesive. 
switching back 2 condoms pill and will save for an IUD."
