I had what they called a chemical pregnancy last month. On August 4th I got a positive pregnancy test and then started spotting the next day. I bleed off and on for a couple weeks and then the dr did an ultrasound on the 22nd of August and it showed nothing in the uterus and the urine test at the office was negative. I have not a period since then yet and my boobs have been a little tender and sometimes feel tingly in my nipple area along with a headache. Should I go ahead and test or just wait it out since I haven't bled since about the 15th or 16th of August?
