Hi, so I recently had sex, as in 3 days ago. We were using a co Dom with spermicidal lube on it and it broke, we noticed moments later and pulled out. He had not ejaculated, but Precum was evident. Roughly an hour later, we went to the drug store and bought EC (Plan B) my breasts are tender and feel more full, with the veins being more prominent. I'm experiencing loss of appetite and nausea, but that could very well be due to stress. The majority of my symptoms are possible side effects of Plan B. Ease my mind, please? In terms of ovulation, I recently started a period tracking app and recorded last months menstrual activity. It says that I would have ovulated 8 days before intercourse.
