So in waiting for my period so I can start IVF, I was meant to be due on last week but still haven't come on, it's impossible for me to be pregnant, just very unusual because I'm never late. I'm worried that the clinic may forget about me:(. I can't sleep just thinking. I don't know why I haven't come on:(. Feeling like nothing's going right. Sorry for the negative post just wondering on what I should do:(. Thanks in advance.
