Period 2 times in one month and a week later itchy sore nipples.

Jessika

I had my period 2 times this past month and now since I changed it on the app I am apparently in my ovulation cycle now . I have had sex a numerous amounts of times the last month as well as the last week. But today a week after my last spontaneous AF my nipples are so sore, itchy and I feel like I am going to get my period again... but it’s not for another 2 weeks ( says the app) has anyone experienced this ? Is my body just messed up after coming off the pill 4 months ago? Or maybe preg?
