If you have been having symptoms after taking salad that's 7 months overdue, the first suspicion is food poisoning
. Please consult a doctor immediately and get evaluated for food toxicity. You should drink plenty of water and fresh juices and eat healthy freshly prepared hom food. You might be given medications. Talk to your doctor regarding precaution to be taken and if you can feed your breast milk to your baby while on medication.
Hope this helps
