14dpo. Faint line at 12dpo now bfn

Last cycle I had a miscarriage. This cycle I tested at 12dpo and got a faint line(FRER). Today tested again (Frer- 14dpo) as my boobs aren't as sore and the line was barely visible. Had bloods done and waiting on results.

I have period cramping but also huge headaches and nausea.

I know its likely a chemical but I guess I'm looking for that glimmer of hope. It's all getting a bit too much, month after month of false hope 🥺😭
