Did an opk on the 13th and it was a faint line, I tried again yesterday and it was even fainter. Anyone any ideas if I already ovulated? It is my second month measuring my bbt and it still looks like magic tot me 😓. Last month I ovulated before my supposed date ( in my fertile widow the 7th but glow said the 10th). My cycle was 35 days (July and August ; after my miscarriage) last time it was 28 days. Glow still uses 35 days, so I'm really confused. Btw temperature is Celsius because I'm Dutch!
