Freaking out

I am now a few days late for my period and I have began to panic. I had unprotected sex with my boyfriend on JUNE 4th and my period started June 7th. It lasted about six days and was not as heavy as usual. We had sex again on June 30th and July 1st. On June 30th before we had sex I had some bright red bleeding, I wiped and it went away, I thought nothing of it! after we finished round one he made a comment about me being creamier than normal. I went to the bathroom and I got a nice glob of what appeared to be cervical mucous. I let him feel it and we moved on. We had sex again unprotected and now I am a few days late for my period. I had some intense cramping about two days ago but no blood. I been extremely moody and my nipples hurt so bad, I’m always Nauseous around my period so I thought nothing of it. I been convincing myself it is no way I can have a baby as I am 26 and never been pregnant before. I want to have a baby but I am so scared to take a test and it come out negative. The only change is the last two weeks my head has been hurting so bad all day long and I am sleepy more than usual. Please help me make sense of all this!
