Veronica • 1 ectopic pregnancy at 11w 4d//2 miscarriages. Currently TTC my rainbow baby with one fallopian tube, endometriosis & PCOS! ✨🖤🌈👼🏻

i’m 13dpo. last week the line was lighter than this. i know ovulation test can detect pregnancy and ovulation. is it darker because it’s starting to pick up the hcg hormone?
