Last month appearantly I had a spotting related to implantation, but then appearantly had a miscarriage, due to it being a chemical pregnancy. I am trying to figure out what is the difference in implantation spotting and regular menstrual spotting? Being that again this month it seems that I am spotting but it is still not a full blown period. Anybody has experienced anything like this or any feedback on what to think? I tested on the 20th of July and it was negative. Spotting started on the 24th of July, should I test again? My period first cycle was July 1st, that was full blown period after the odd three day spotting, I had 4 days before that.. which would have been the chemical pregnancy. Any feedback on what to think?
