Unprotected sex 11/3 & 11/10. period due 11/7. 11/13 light pink spotting once. 11/14 only when i wipe brown blood. and my calc say i ov today puzzled?

So am I: If your period was due the 7th, than you would not be ovulating today on the 14th? It appears your dates are off. Hopefully, if your period was truly due on the 7th, than having sex on the 3rd and 10th would be unlikely to get you pregnant. And if you were in fact supposed to ovulate today, those sex dates would be getting far away as well. The 10th is cutting it close though.
