Ttc and testosterone injections :(

Hubby started injections in January and I've read they are like a male birth control. We were pregnant when he planned to get on it and I ended up losing the baby in mid decemeber. He officially had his last shot on Friday and I'm so happy and lucky to have a husband so willing to sacrifice for our hopefully growing family <3 hoping for our rainbow soon this is my third cycle since the loss ! Anyone have experience with a husband or SO who had took TRT ??
