Question about pork

I made some boneless bbq pork ribs and boiled them for about 40 minutes and then baked them for about 30. I don't have a meat thermometer and I'm relatively new to cooking pork so I want to make sure they are safe to eat. Especially since I'm pregnant. When I cut into the ribs the middle is white and is obviously done. The outside however, has a pinkish tint to the meat. I'm not sure if that is because of the bbq sauce or is they are undercooked. I know sometimes pork can appear pink but it's actually fully cooked. Do you think boiling them for 40 minutes and baking them for 30 would kill all the bacteria?
