I had an 'abnormal' result with my first smear too. I went to an OB/GYN who did a biopsy on my cervix, and it came back as a 'pre-cancerous area'. It sounds really scary and I was really shocked, I'm only 23 and didn't think I would have anything wrong, but the ob said they are just cells which MAY progress into cervical cancer at SOME time in the next 50 years, so its not as scary as it sounds! I was booked in to have an operation to have the cells removed when I fell pregnant, the ob was not worried and has kept an eye on it during the pregnancy, but it has not grown or changed at all. When bub is about 5 months I can book in to have the op done, it just a simple procedure (you can be awake or asleep - I'll be asleep!!!) they go in through your belly button and also in through your vagina and "burn" the cells out. Recovery is about one week (maximum) and it's all over.
One way to put it, is you have moles on your skin, which COULD progress into skin cancer at SOME stage of your life, this is pretty much the same but in your cervix. Technology is so good these days that things like this would never have been picked up 20 years ago until it progressed, so don't stress too much, whatever the reason for the abnormal result, you have found it in the early stages and it can be fixed.
If they are just getting you to take another test in 3 months and not doing a colposcopy or biopsy straight away, then it's probably nothing to worry about. If they thought it was serious, you would be whisked into the ob's rooms and tested straight away.
My result was a pretty major one for a first smear, so please don't let my story scare you, I'm just trying to say that even if it is bad (which it doesn't sound too serious) it can be fixed fairly easily.
Good luck and keep me posted.
