In need of some hope

Okay ladies, I am 12 doiui. I have had some cramping since Sunday. So Yesterday (on day 11) I took a FRER and it came back negative. I’m due for my blood test on Thursday. I need some encouragement, some help to get me though or words of advice. I feel so worried it didn’t work and shouldn’t have test ahead of time because I am feeling so down and alone. I just feel like 11 dpiui should have been a positive urine test if it was going to be positive. Needing some one to talk to who understands what I’m going through ❤️
