I'm 6days late. I just downloaded this app and it shows I'm a week late. I've been taking tests and they all come back negative, even the FRER. I have an appt Monday with my primary for a blood test. My periods are always regular and always come on time. I've only been late twice and both times was because I was pregnant. Both times I always got positives even faint ones. So what's the deal this time? I've had some symptoms on and off. I'm not anymore stressed than usual, not on meds, haven't been sick, etc. So why am I late? Could I still be pregnant? Any advice, suggestions, or similar stories are welcomed.
