Late and frustrated

Today marks 6 days late. :( For more than a week, I've had mild cramps, sore/ tender breasts and very mild nausea at random points throughout the day. This morning I took another negative test and I'm feeling so frustrated and sad. I've been married since June and we started ttc right away. I know it hasn't been long, but geez it can really mess with your head and your heart!

Has anybody experienced this and ended up with their bfp? Do I just need to be patient?

If I don't start by Monday, 8 days, I think I'll make a appointment with the doctor.
