Yesterday I took a test, I saw the shadow in person, only on the photo it shows through the blue filter ? What do you think? My cycle is irregular, PCOS stands, now I'm going through treatment prescribed by my doctor, for restoration more or less of a cycle Last time on these pills the cycle was great, so I'm thinking maybe this time too lucky ?? but something tells me that it's just a place under the stripe)
