I'm just curious...I started Yasmin approximately an hour ago for the very first time in my life...could side effects show up now? I read this board a lot so I think it could all be my imagination and I feel ok right now but my left arm aches a little but its not painful or anything.

I don't know about that...that would be an unusual side effect. One side effect I have noticed show up immediately (well, within 2-3 hours of taking the pill) is nausea. If you have that side effect, it very likely will show up shortly after taking the pill.

Hey I just started yasmin about 2 weeks ago and the first like anything side effect that I noticed I was kinda just blah for a few days (like -3/4 days after taking the first one) , but then everything got back to normal within says after that first week and a half.
