How early does it take for the symptoms to come?

Hi me and my boyfriend had sex multiple times the first time was on dec 30 and it was unprotected and he did not take it out. He said I could not get pregnant because it was not his first time "coming" so it was not as strong.. the next day I was sick with a horrible headache and I had diarrhea and was also constipated for a week. The second time we had sex was on Jan 2 unprotected and once again unprotected and this time when he did not take it out he came and it was his first one of the day.. since then I have been extremely tired my breast are somewhat tingly and my face has broken out. I've taken test and they said I'm not pregnant but it has also been only 1 week since I had sex so is it to early to know? Are those early signs of pregnancy? And how early does it take for the symptoms to come?
