Faint BFP now that im 6 weeks?

Sophia

Ladies I need some advice. I tested last week (Wednesday) and got 2 BFPs with Sainsbury own brand. Couldn’t quite believe it so tested it again the next day and got instant BFPs with Clearblue. I’m now 6 weeks and wanted to test again (this morning using FMU) and now the test is fainter then before. Has anyone has experience of this? I have all my pregnancy symptoms and had no bleeding or anything.
