discharge.. sorry if it's TMI

I am only a little over 4 weeks pregnant and since ovulation I have had a slight discharge sometimes white and creamy sometimes clear. Doesn't really have a smell if anything it's oddly a sweeter smell if that makes sense. Anyway it's freaking me out because I keep thinking it's my period deciding to show up and so I have been running to the bathroom constantly. I know this can be normal I just wanted to know if anyone else has this or if I am crazy already haha
