stupid sex ed question

cl

i had protected (with a condom) sex during ovulation this month. he didn't come, and the condom didn't break.

however, i had some spotting in my ovulation discharge a few days later, and i just had some thick, cottage cheese like discharge that does not itch.

could it be implantation bleeding and discharge from being pregnant? a yeast infection even though it doesnt itch? any advice or peace of mind would be cool.
