So, I'm on day 3 of the pre op full liquid diet. I'm due to start my TOM any day now, is there any reason that the sudden restriction of calories would shock my body into skipping a period? I had a slip up when I moved and fell off the wagon with my BC pills, now I'm waiting for the cycle to start over (aaaaany day now) so I can go back on them. I've missed periods in the past, but they've been pretty regular lately. I had my pre surgery labs done yesterday, so I haven't heard back from the pregnancy test yet. But I am just paranoid that after waiting a whole year to do this, I'd have to put it off again. So... if there's anyone who has any insight or suggestions, it'd be greatly appreciated!!!
