TTC for 3 years...need advice. LONG post!

Kristal
So...I used to have pretty abnormal periods. Either really long, really short, really heavy, or nonexistent. I never knew what to expect. I'm a curvy gal so this was always blamed on my weight of course. But for the past year or so though they've been normal. Not sure what caused the shift but I'm not complaining. We've been TTC for about 3 years now and it's been hard. Especially since my SIL just had a baby girl (who I adore). I just always thought we'd raise our babies together. Anyway, I've had all my fertility tests done which were normal. He just needs to get his done before we can be referred to Shady Grove. I'm getting ready to try acupuncture because I've heard wonderful things. I just don't know what else to do. Perhaps we're not having sex enough or at the right moment? Perhaps there's something wrong with him? I'm just sitting here 3 days late and AF has yet to make an appearance. I've had slight cramping but no blood. All tests since 2 days before expected AF have been negative. Though I try to be optimistic I just know AF is gonna rear her ugly head any time now. Any advice would be greatly appreciated!
