Q&A: Could I get toxoplasmosis from undercooked meat?

I have questions regarding toxoplasmosis. I am 26 weeks pregnant. First, my husband grilled lamb medallions during my first trimester and there was a bit of pink in the centre. Would that be considered undercooked and does it pose a risk? Second, I purchased "Cook's" Cured, Smoked PARTIALLY cooked ham steak (sealed package) last night and I assumed it was FULLY cooked. So I heated it in the microwave for 2 min. Unfortunately, my husband noticed it wasn't fully cooked. The instructions said to microwave for 4-5 min. Neither of us feel ill or have a temperature but I know that toxoplasmosis can take weeks to show up. Should I be concerned with the baby's health? I have been raised with cats from a young age as well. Is there a high chance I could already be immune to toxoplasmosis? Thank you so much for your response. I am so worried!!!
