I got a vfl on pregmate Wednesday and it has got darker today. I tested with fmu. On the same one o used a first response 6 day sooner digital and it was a BFN

I recently had a chemical pregnancy in January and I’m so scared it’s happening again

What does this mean

I’m 11/12 dpo I used OPK but I only tested once a day

The top one that’s stark white was Tuesday which was clear negative

Has anyone had positive on cheapies and BFN on frer digital and had a successful pregnancy
