Is this possible?

I was put back on the birth control pill 2 months ago after my PCOS, type 2 diabetes diagnosis and my lack of periods. I was also put on metformin 500mg and began dieting last month because my husband and I were planning on trying after my October pre-conception appointment if my blood test results improved... I am on day 4 of the placebo pill and there is no bleeding in sight. I had spotting 6 days ago but it was extremely light. I have also been extremely tired and nauseated the past few days. I had been very good about taking the pill daily but sometimes I was a few hours off on time of taking it. I wasn’t worried about pregnancy until I woke up from a dream about twins 😂 today I ended up throwing up and ran to Walgreens for a test.. they only had blue dye in stock and I took it as soon as I got home, immediately it showed a vvvvfl. Then I began reading reviews and realized it may be false but the line is thick and blue in color in person 🙃 has anyone had experience with getting pregnant on the pill? Thoughts?

I will test again in the AM and if I get another vfl I’ll call my doctor.. I am just so anxious.
