I'm 14 dpo today and extremely worried that I am going to have a chemical pregnancy I have become obsessed with line progression since I got my bfp at 10dpo I was using internet cheapies and found they didn't show a clear progression although the line was darker and thicker at 13dpo I decided to buy some frer and took one this morning (14dpo) I will test again in 3 days time to check line progression, should I use the photo I took within the time limit or one from a few hours later as this was darker? No nasty comments please I am very concerned
