Hello, I'm new here. Just had a question. Me and my partner were together on Dec 9, 10, and 11th. We used condoms each time we had sex. Also, each time he checked the condoms afterwards to make sure there were no holes in them. On the 11th I took a plan b. I was using I diffrent tracker and it said my cycle was due yesterday. The tracker also said I ovulated on the 9th. I took a pregnancy test earlier this week and it was negative. My period is considered late by the tracker. I know plan b is suppose to delay ovulation, which can throw a cycle off. I am thinking I ovulated much later than my app suggested, therefore delaying cycle. We were very careful, I know condoms are not full proof. I'm extremely new to sex...yes in my late 20s. I just wanted t know if you all think it's just the plan b? My breasts are not sore, my stomach is upset. There is some naseua, but it's normal for me to get that during pms. That's been happening since I was 16. Any thoughts?

Update: my cycle was due yesterday on the 26th..I spotted and it came the next day the 27th
