Hello I was looking for some advise really I am thinking about trying conceive . However I am underweight and am not able to gain weight have had every test done possible which has confirmed I'm healthy although I do have a thin womb lining and me and my partner Ttc for 9 months before then stopped trying. Also my periods are very heavy and irregular . Has anybody else been very underweight with a thin womb lining been able to conceive without help ?
