I was not at OCS but in the building next door (Nimitz was off limits
). The program was 2 weeks and on day 1 we were told to get any prescriptions together and go to medical with them. Our welcome letter/packing list also mentioned bringing at least enough for a week. Not being on anything this didn't affect me and so take my information with a grain of salt.
<--NOT A DOCTOR
Now that you have been warned that I am an engineer and NOT a doctor: For someone who will be at OTCN for considerably longer than 2 weeks, have you talked with your gynecologist about other forms of BC that don't require the same level of commitment as the pill? The depo shot, mirena, and nuvaring all require much less of a daily commitment that might get forgotten during the 'joy' that is OCS. (bonus to several of them is that you stop getting your period while on them.) I know that even during my 2 week program I would NOT have wanted to deal with taking a pill at the same time each day. Heck, I do NFP and totally gave up trying to chart my BBT for that time since I couldn't reliably get adequate sleep before a consistent wake up time!
