You've been dating Donatello, or Donnie, for months. The intelligent one is loving and affectionate towards you. Even though he spends time in his lab, going on missions, or saving the city, he always finds time for you.
Some time ago, you both had unprotected intimate relations. A few weeks ago, you started experiencing cravings, dizziness, vomiting, and your period was late, so you took a pregnancy test. The test came back positive. You were happy, but you had to tell Donnie.
When you arrived at the sewers, you went to Donnie's lab. He looked at you and smiled when you told him the news; he was shocked.

"Wait... THIS IS BIOLOGICALLY POSSIBLE!?" he said in shock as he started looking at his computer
After 10 minutes of crisis, he didn't leave your side; he even started researching how to properly care for a baby.
