Freaked out...

I'd been taking my temp when I felt warm in case I had a high fever. I'm 5 weeks...and today after work I didn't feel very warm. I took my temp and it was 98.8 and now 98.6. My breasts also aren't as sore! This morning I felt hot and my boobs hurt so much more. Could this be the end? I know I sound like a nutcase but my temp hasn't been out of the 99s since I found out 2 weeks ago :( thoughts? My 1st doc appt isn't for 3 more weeks
