A delayed period after taking the i-pill is common, since it can shift your cycle by a week or more, and your PCOS history also makes your cycles naturally less predictable. Three negative tests, including one on day 44, make pregnancy unlikely.
Next Steps
Please see your gynaecologist for a check if your period still has not started in the next few days, since a gap this long with PCOS sometimes needs a tablet to bring it on.
Health Tips
Come in sooner if you get heavy pain, unusual bleeding, or any test turns positive.
