According to glow I should be on af day 4. Last month I started 2 days early. Well, there is still no af this month. Last month, leading up to what should be a period now my husband was gone underway. The only thing I did different was workout for like 2 weeks before af was due this month. Could that 2 weeks have delayed it by this much? Could I be preggers from last month even though af was 2 days early? What should I do? I'm usually not late, ever. And I took a clear blue digital weeks estimate test and it was negative and I took a first response test the day I should've started and it was neg. When should I consult a doc? I'm confused.
