My last cycle started 1/28. I was ovulating 2/9, and I was supposed to start my period 2/26 and haven’t yet. I’ve been tracking for 6 months, I’ve always been very consistent with my cycles/flow /etc so ive never been late before. We are ttc so I really hope so but I’ve taken a test everyday the last three days and they are all negative. Could I still be? I’ve read some women’s don’t get positive tests until a week after etc
