You are a confusion about your own history.You first said that that '12 days after ovulation i started off with spotting, then i had bleeding which was lighter than my period and no cramps, pain or any other symptoms. This lasted for about 3 days then i went back to spotting again which lasted less than a day.'These were your exact words. then you said that it was only two days.you keep changing your history.i dont care what other people are saying.symptoms in early pregnancy
occur in few people and definitely after 6 weeks.Implantation
bleeding occurs 3-4 days after fertilization.So by your so alleged dates it should have occurred around 22nd dec
plus minus 2 days.The bleeding should have been minimal.lasting a day or so.Apart from nausea
its too early to have other symptoms.If you missed your period then you should have taken the test instead of speculating.I have given you an answer based on medical knowledge.
