Sorry for the long post but hoping for some sort of advice as not really sure whats going on. I've been tracking ovulation using CB since August and it has been like clock work, always at the same time in my cycle which is always 28 days.
My last period started on the 17th nov, i got a delayed flashing smiley on on the 30th which lasted 9 days, no peak as it went back to blank - i was testing twice a day. I thought af would also be delayed but two days ago i got black blood spotting which has increased but still nothing like a period. Seeing black blood is concerning and i've never had this before, i was wondering if anyone had a clue what this could mean? We couldn't dtd this month and i had my first vaccine dose in October (but nov period came bang on time). We want to try this month.
