Pregnancy symptoms but Negative test?

*TMI* Last night when i took a test after i wiped there was what looked like CM with a little blood mixed with it. It kinda looked like clear snot with the blood throughout. I only saw it that once and nothing since. I have been havin' headaches, pullin'/fluttering sensation in my lower stomach with twinges off and on on both sides and just below my belly on. I have also been gettin' dull back aches, unable to sleep for too long, peein' more often then normal, and blotches like im breakin' out on my face. I thought that perhaps AF was soon to show up but now 14 days later it's still a no show. I know that AF and PG symptoms can be very close...but this is totally different. I don't get "twinges" with AF symptoms. Curious if the test just didn't pick up the hormone and im actually pg or if this is one MESSED up AF that isn't gunna show. Im TTC #1, no meds, 26 years old and in good health. Thanks for replys...and BABY DUST!
