EDIT: I realize now that I wrote 8/22 and 8/23 on them. I have NO idea wby I did that. I guess it was just too early for me, idk 🤦‍♀️ But they are from 12/22 and 12/23.

I'm now 4 days late for my period. I took a test yesterday miday. The control line is really faint, but the test line is super dark. I took another one first thing this morning. I took the FRER rapid results in 1 minute. The one yesterday showed up immediately. The one this morning took about 2-3 minutes to show up completely, but the test line was really faint within 15 seconds. Are these tests valid?
