Don't be discouraged newlywed. The cramping can be a good thing. I've been cramping too. Today probably the worse...not that it's horrible, just light/mild cramping and I'm 14dpo/iui and I really don't have any feeling of af coming on, which by now I do, but who knows. When are you supposed to test?
Frustrated, what was your lining and hubbys count? Low numbers don't necessarily mean it can't it happen. I don't think they would have done the iui if your lining was too thin, so I think you'd be ok there.
AFM, still living in maybe land playing the waiting game. I've been feeling like something's a little different this past week. In part because I don't have most of the symptoms I normally do, or at least they don't feel the same as usual. Hoping I can't take that as a good sign, but we'll see.
