Hi, Not sure if this is the correct forum for this? I am 36 and have two kids. I would like one more before it?s too late. I have been trying for just under 2 years with no luck and my second child also took a year to conceive. I would like to stop TTCing at some point but I also want one more baby. I have had my day 21 tests done a few times at the GP. Each time I bring this up he keeps on sending me back for day 21 tests!(which so far have been really good). I think he looks at me and wonders why I want another. Meanwhile I am getting older and so are my kids. Any advice on what to ask him next? Should I have day 1-4 bloods? My thyroid results have been 5.1 and 3 but he says this will not affect my fertility. I just want to either get PG or give up on this dream of DC3. I don't want to be still trying at 40. Any ideas? Thanks
