Hello, I would be happy to help you with your question.
If you had conceived on Friday, it is very unlikely that you would be experiencing pregnancy
related symptoms this early. While the chance of conception is still present, these are likely just cycle related symptoms that are reassuring in terms of indicated that you DID ovulate. Since you have been trying to get pregnant, make sure that you check a pregnancy test at the time of your next period.
I hope that this helps. If you have more questions, please click on "ASK ME A QUESTION" link above to directly ask me a question!
