My current cycle is 41 days. I have only had 1 regular cycle for the past 7 months, but I haven't had my period this delayed since January (55days), and I wasn't sexually active then.

This app says my period's 8 days late. I had unprotected sex on the 24th, but he did not finish. We also did not use protection for the first five minutes or so on the 10th and 17th (he did not finish), then proceeded to use protection until we both did.

I took a pregnancy test yesterday (11 days after sex), it came out negative. I took another one this morning, and also came out negative. I have felt some minor cramping (no other symptoms), but still no blood.

Any thoughts?
