My period just started again, only seven days after the last one ended. This is really annoying me. I had my third DC in November and while other breastfeeding mums in my birth group are rejoicing at 18 months since their last period, I've been having them every two weeks since December. I went to see my GP thinking she might want to do a thyroid test or hormone tests but her opinion was that it was fine. I was never clockwork regular but before this the absolute shortest I ever had between periods was 27 days. Now it varies from 13 days and up. Honestly I feel like it never stops.
