My last period was from May 4-9 since yesterday after noon I have been bleeding bright red blood and at time with clots and enough that I’m having to wear a pad. Any idea what this could be?? Ovulation spotting? Implantation? I’m at a loss. My partner and I have had unprotected sex in the past week but have been using the pull out method. My app says i am at my highest ovulation point tomorrow but could I have conceived in this week?
