Advice

Hi! So we’ve been ttc for a little over a year with no luck. This cycle was supposed to start last Sunday but still hasn’t started making me almost a week late. I’ve taken two test (one Sunday and one yesterday, both were negative). I’m usually right on target and not a day late. Has this happened to anyone else? How did it turn out? I’m not really sure what to think of it. Thanks for any advice and help!
