Hey ladies my metallic taste is back again😫....at this point idk what it means cause it's been 2 weeks since the last time I had it and when I had it the last time it lasted for a week or two😐 but I took a test when it was my expected period and got a bfn😣 but turns out I was about to ovulate🙃(got dull pinging o pains May 7th) so yah now it's 2 weeks later and I have the metallic taste again😧. I'm not sure what it could mean now 🤔
