The pregnant Teen Mom 2 star posted her ultrasound picture on Sulia Friday.
"I circled where the baby is located since it's really hard to see," the 21-year-old wrote. "I'm 7 weeks now and was 6 weeks and 2 days when the ultrasound was done. if you look closely you can see on the bottom left hand corner it tells you how big the baby is and how far along I am. So excited!"
Jenelle told MTV Act that she and husband Courtland Rogers "are happy and excited now"; their baby-to-be "wasn't planned, but it happened so we're taking it as we go."
Jenelle and Courtland both have children from previous relationships, neither of whom live with them.
"I know a lot of people will say we're not ready, or judge me from my past. I want to prove to everyone that I can do this," she said.
We wish her the best.
