Fingers crossed!

Took test because period was 2 days late, had strange sharp pains, then SPOTTING on and off for 3 days. Took another test the following week , still negative. I've now had random nausea from cooking, back aches, sore and swollen breasts , metallic taste in mouth, and have a dull ache in lower abdomen that comes and goes, sometimes like a tight feeling... Hopefully I'll get my answer soon!
