I am 12 weeks post partum and I had light bleeding for three days on January 28th 29th and 30th but it didn’t turn into a full blown period and the color went from pink to pinkish red back to pink again. According to glow the bleeding would’ve been 9dpo. My period was supposed to be yesterday but didn’t show. I’m honestly wondering if the bleeding I experienced was implantation bleeding or a irregular period? I took this this morning with fmu. Showed up within 2-3 minutes Thoughts?
