Well, went to the doctors, she did a urine test and it was negative... but she said it still might be a bit early since I was only 4 days overdue for AF, not sure how far out the test she used works from. She gave me a referral for a blood test, and if AF still hasn't arrived by the end of next week to go and get it done. She also suggested to start taking folic acid/folate, so have started doing that.
Grabbed a HPT yesterday when I went shopping, spent about 10 mins in the aisle just waiting for people to disappear..lol
Still have really tender breasts, more than they would be if it was just AF, so I dunno

So there's still hope, if not there is always next month
