Birth control

Taryn

LADIES!! I need your help! So my SO just got out of bootcamp and we got married! Just a little one and we will have the big ceremony next year as our one year anniversary. But I am on the pill and just finished my period. Well we consummated and I started to bleed like another period after 12 hours. (When I woke up and took a shower it was like I was on my period again.). Is this normal or cause for concern?
