hi im 28 years old and im am trying to concieve. i ovulated 10 days ago and i have been experiencing cramping in my lower back on the left and in my abdomen, the pains come and go and seem to be worse at night. my breasts are also very sore and tender and feel like rocks. i have no discharge. i have had sex every day during this cycle. i already have 2 children, but did not experience anything like this before.
