Does Plan B work near ovulation?

MrzL

My DH is getting deployed and being pregnant alone is not what i want right now so, we had unprotected sex multiple times 2 days in a row. I took this pill after maybe 18hrs. Now, im worried because according to this app i have 5 days till ovulation but i took this test and it seems to be closer than i thought. This happened to my best friend and the pill failed her...just wondering if you ladies have any experience with this. Thanks ❤️
