Your
beta hCG blood test earlier this month came back less than 0.1, which rules out pregnancy from that encounter. The bleeding that started on November 1, matching your usual flow and pattern, is the withdrawal bleed the medicine you took was meant to bring on, so this is a genuine period.
Next Steps
You don't need to repeat a
pregnancy test for that encounter. For your next cycle, talk to your gynaecologist about a regular contraception plan so you don't have to rely on emergency measures again.
Health Tips
Go back to your gynaecologist if this bleeding stops within a day or two, is much lighter than your usual flow, or if your next period doesn't arrive on time.
