Safe a few days before ttc?

I am aware of food dangers and such while pregnant; but I’m wondering about a few days before trying to conceive. I get an ultrasound this Thursday to make sure everything is good before we ttc again. [Long story short: I had a missed miscarriage in November, bleeding and spotting didn’t stop for months, finally got a D&C; in February, then found clot and cyst in March and took the tissue clot out, and am checking me this Thursday to make sure cyst has either shrank or gone away. Life has sucked since I would have been due June 7th]. That being said, Ive had a few pieces of jerky this week, and two lunchmeat sandwiches this week. If the ultrasound is good Thursday, we are gonna ttc because I am feeling like I should be ovulating this week (and glow thinks so too). I am beyond anxious! I really want to start a family and this has been a long grieving process. My husband and I are ready to move on and try again. So; am I at risk if we do conceive, because I had a few pieces of jerky and lunch meant sandwiches 2-3 days before??
