I am just really not sure what to think. I started taking Metformin 500 MG December 27th but started noticing slight pain in my stomach December 30th. Since then I’ve also had slight back pain, Nauseous feelings, and very tired.  There’s also this weird fluttering feeling in my stomach that I recognize from two pregnancies that I’ve had before which unfortunately ended in early miscarriages. I took a first response test on January 2nd and was very surprised that they were negative.

Because I kept having other symptoms I decided to go get some cheaper test A few days later which I felt like I kept seeing a slight faint line but wasn’t sure. When I came back after 10 minutes the line that I thought I saw had gotten darker. This really took my mind into crazy mode because I knew it was the lien getting darker after drying. So I Took another First Response test which came out negative last night. I waited and took The second test this morning and got a very faint line.

I guess my question is how many days after a missed period does The test line start to get darker. I do have PCOS so regular periods are normal for me.
