Does anyone take anything to strengthen their endometrium lining? I think I don't have sufficient tissue. My af only lasted one day this last time and normally they are 3 days maybe 4 at the longest. I have had at least two maybe three chemical pregnancies in the past seven months that I know of. I haven't seen an Obgyn yet since I'm not due for my yearly until August and my insurance only covers one a year if you aren't pregnant. :/
