I would be furious with your aunt she is so wrong! I hope you know that 36 weeks IS considered term and i hope your baby was OK, obv i dont know you x My DD was 11 days over and i had three sweeps and did EVERYTHING my MW advised to help things along because I was 1cm and contracting since my EDD so no even if you tried you couldnt have caused it.
