Becoming pregnant symptoms and conditions

I just started using Nuvaring a week ago... and have experienced some strange side effects. The day after having instered the NR I woke up with a fever, dizzy and extremely tired. It's been a week and I still feel as if I have a fever and am very sleepy. Has any one else experienced these side effects?
Also, does anyone know if the Nuvaring is effective the same that you insert it? I mean, if I put it in today in the morning and have sex at night, am I protected against becoming pregnant?

I am 31 years old and have been on Advair for atleast 5 years and have experienced a 25 lb weight gain despite all attempts at losing it, bruising, joint aches and pains, fatigue, and "lung pain." I have made the decision to wean myself off of it at this time especially because I plan on becoming pregnant in the near future. I need to search for alternative medications, preferrably not a steroid. Any ideas?? Thanks, Staci

I had been taking Yasmin for 3 years. I didn't really notice any side effects, but in the last year I started to get really grouchy and mad all the time. Also I had very little sex drive when I started taking them. I have only gained about 7lbs in those three years. I just came off Yasmin July 14 in hopes of becoming pregnant, even if I don't become pregnant I hope I will stop being so moody since I am off of them. Also my sex drive has came back in just 2 weeks after stopping. If you are trying to decide on a bc pill Yasmin isn't that bad, especially if you compare them to other pills.
