advice please

So a little back story on me. I have never been regular in my life I would usually got anywhere from 2-6 months with out a period. This last year I have been some what more regular lime every 35 days I would have my period. 

Me and my husband got married on October 29th and we decided to wanted to start trying to have a baby that night and we did. Well my last period was on October 1st. This is the first time all year I have been this late. I have taken 2 at home pregnancy test both came back negative so I decided to go to the doctor and got a blood test done well it came back negative. I haven't been having strong symptoms but I have been having a few like being nauseous when I smell certain foods and nauseous after I eat. I was also certain that I was pregnant. I even woke up one day and was like it's a girl. I haven't been pmsing either which I usually would by now. 

Could it be to early to tell? Even with the blood test? 

I guess im going to wait a couple weeks and see what happens.
