Faint line on day AT due

[Purplestar2]

Hi, first time poster but been lurking around in the 2ww!

My AF was due today, normally have spotting beforehand but nothing this month, also have same symptoms I had with my son so tested this morning. Annoyingly all I could get was a sainsburys blue die cross test.

Tested this morning with FMU and I had a very faint but visible vertical line within the 2 minutes, same width as horizontal. My question is, should it be a stronger line on AF due date? I'm worried something's wrong.

I can't seem to find an option to upload pic?!

Thanks!

There's a little paper clip you press that you can attach a photo to

Hmmm I've tried to post a pic twice, it says success but not appearing?

Sainsburys tests are NOTORIOUS for giving false positives. Get a first response. I am not saying yours is a false positive, not at all. But test with a first response if possible. The faintness doesn't matter at all. Mine were always faint and I'd test a day or two after AF was due. One of my faint positives is next to me trying to tell me the plot of a film while I'm typing my reply to your post. So don't worry. A positive is a positive, even if it's faint. But do try a different brand of test. Best of luck!
