Okay so this month my period was on the 25th December. On the 26th I started spotting and continued to spot until the 1st January. It never developed into a full period which concerned me so I took a test. It would have been around 16dpo when I took this test, I am now 17dpo.
I took the test last night after a 4 hour hold. It was only a cheap Tesco one as I wasn't expecting to actually see anything, and I didn't initially. I'll attach a photo of what it looked like after about 5-10 minutes (second photo).
A couple of hours later I went to bed and checked it again, only to find a faint line (first photo). I turned up the saturation and it was blue, I also inverted the picture and it came up clearly orange.
Now I know Tesco tests aren't the most reliable and I've absolutely had evaps before but NEVER have I had a blue line appear, even after the time limit. So what's everyone's opinions? Should I be freaking out and going out to buy a FRER or not lol?
