well, as you can see im new to this board, as this is my first post...but ive been lurking here for awhile now.
just to start; Nora and I are an amazing couple, we never fight, never argue, and we know we are right and ready for each other.
so here's the story.
My girlfriend and i have been dating for over a year now, and back around christmas we started discussing sex, neither one of us has had a prior relationship that lasted longer than a month, and neither one of us has had any sexual experience, so it was definatly a nervous and intersting conversation, but after talking about it, we realized it had been on both of our minds for a while, and we decided that we were ready and that she would talk to her mom about getting a doctor appointment to get the pill, her mom btw is really cool about everything.
anyway, today starts week 4 of since she started taking the pill, and she says she needs to finish week 5 before its safe. So i guess my question is, is 5 weeks enough for everything to become effective? she's on Aleese-28 i belive, and i know she takes it everyday at the same time because she has a few other daily meds that she takes with it. So if this is correct, im guessing we get another 2 anxious nervous weeks before we...well you know. 
Also, when we make-out, i sometimes finger her, which she seems to really enjoy, but she doesnt really want to talk to me about how it was, other than it was good. I have a problem telling when to stop or if i should keep going because the only physical signs i get are fast breathing, right before a deep exhale usually then her breathing goes back to normal, which i guess means she has climaxed but i really have no clue, its not like a male where you know, its obvious. anyway...any other clues of what to look for and how to tell when she's had enough, cause i cant seem to get much information out of her.
well, she confirmed, and she was a little off, so on friday we are getting togeather...
when we first started discussing the subject, i was really nevous, but now im not, we know every part of each other, and i cant even describe how much i love her, so right now im really not that nervous about it. things may change on friday but, we'll see! lol
The only thing im concerned about now is how to make the whole day a wonderful experience for her. Im not sure what i want to do to make it even more special for her, (and well me too) Any suggestions would be nice.
She needs to ask her gynocologist to be absolutely certain when she will be at full protection.
But (now, preachy time, sorry) there are NO 100% effective methods of birth control. Most are around 97-98% effective... this means that out of every 100 times someone uses this method (and I'm not talking about just you), there is a good chance of 2-3 pregnancies. To protect yourselves even more, you should consider using condoms and a spermicidal foam or gel. That's just my suggestion and entirely dependent on how badly you don't want to be parents at the moment.
As for her lack of communication during sex (or whatever)... the only way you are going to know for SURE is if she tells you. She needs to understand that there isn't anything wrong with letting you know what feels good. You might try having her put her hand over your's and guide you. Everyone is different, so you kind of have to help each other find your specific trigger points.
Have fun and take care.
To answer your question on whether the pill is effective after 5 weeks, the cycle is actually 28 days, so yes it will be safe. For more information you can go to this link: http://www.fwhc.org/birth-control/thepill.htm
As for signs on whether she has orgasmed, one sign is to feel her vaginal contractions around your finger(s). When she orgasms, her inner muscles will contract and spasm around your fingers in an irregular manner, some women have a few, some have a lot, it all depends. I hope this helps, take care, relax and have fun with your girlfriend:)
