Interesting thread. Like Kosh, I would probably have been classified as underweight, until recently. I am 5' 4" and for most of my adult life have always hovered around 7 - 7 and a half stone. I believe this is my natural weight as I am a very small frame. I managed to conceive my son at the age of 39 successfully and always felt my weight was not a problem because I had regular cycles. They even continued while heavy marathon training (around 70 miles a week) and my belief that I was at my natural weight was backed up (in my mind) by the fact that I had training partners who were a stone heavier than I was and experienced amenorrhea. All changed when, at the age of 42, we decided that we would like to give our little boy a sibling. Realising time was short we paid to see a consultant obstetrician (outside NHS) and I was incensed, not because she commented that I could probably do with putting a few pounds on to enhance my chances (fair enough, possibly good advice), but because when I told her I ate a full and balanced diet, ate till I was full and also had a sweet tooth too, her response was, 'That's what they all say'!!! How patronising is that?! Unless someone presents as seriously over or underweight to a point where it will have implications for their fertility and their ability to carry a baby successfully surely it is right that a Dr should not pass judgement? I felt very smug when I fell pregnant a month later with no help from her
Sadly I mc at 12+ weeks last November and subsequently decided to gain some weight to see if she was right. I am now 8st 2 but after 5 months ttc again without success I started exercising again and will be happy to lose some of the weight again. My body just did not feel as though it functioned properly on eating my usual diet plus extra helpings of cakes, ice cream etc (loved it all though!) and not exercising, just so that I could say I was a few pounds heavier.
Forgive my rant, I am wound up whenever I think of the Dr and her impact on me! What I really wanted to say is that I believe we all know what feels right for our own body and that is different for everyone. Unless you're abusing it in the process, it will function best where you are happy and feel 'well'. Who cares if you are 'curvy' or 'fluffy' or 'skinny as a rake'? If your body is working and you have evidence it is ovulating, how much difference can a few pounds either way really make......?
