Late period, but have negative pregnancy

On December 29th 2006 I found out I was 5 weeks Pregnant, I had a pregnancy test done right around the time i should have gotten it and it was negative (Dec 23rd) on the 29th, I took another one and it was postive, than a blood test but my hcg was only 209. On Jan 7th I had a miscarraige and passed everything naturally. Exactly one month later, (Feb 7th) I got my period. Me and my boyfriend had sex during my period....and on the last day of my period (feb 12th) he came inside me. It is March 12th, and I still have not gotten my period. I have taken into consideration that there is only 28 days in Feb, which would make me 3 days late. Although it has not been that long, my breasts are soar and I am having a thick clear sticky discharge...which I cant be ovulating cus I am suposed to get my period. I have taken 2 home pregnancy tests and is still negative. Could I be taking them to early? Could I still be pregnant even though the test is negative? And is that discharge normal? Please help

Discharge is usually a sign of something hormonal going on, pregnancy, ovulation or a change in hormones from your miscarriage. As far as the negative, test again in a week.
