I Dk!!!! Symptoms ?

Megan • Mommy of 2 girls && one boy 💙. One angel daughter . Step Mom of 2 boys 🤞❤️
I have two kids already , never thought i was pregnant with them . 
I was due for period today and nothing , last 3 days I've had brown streets here or there . Maybe two a day but that's it . Really only wipes from bathroom breaks . I have cramps though ? What is going on!
