You seem to be really trying to get help with your question but you really don't say too much. Not sure at what time past your period you can conceive, thought it was a week, but not sure. Try googling, at what week or day after my period is done can i get pregnant? I google everything i don't know or wanna know. Headache and cramps? Not sure if those are symptoms of pregnancy. I never heard of them. If you want to know for sure, pick up a test or get tested at your doctors. Let me know how you make out.
