What do you think?

So Sunday my husband and I had sex there was a lot of pressure in certain positions. The next few days the pressure continued and on Wednesday I had awful cramps all day long. On top of this I have a cold and headache everyday along with being nausea.  I've been peeing a lot more and my back has been killing me along with being exhausted. I'm paranoid that I'm pregnant it's my every other thought. I'm not due to have my period for another 5-7 days. What do you think ?
