i had unpprotected sex with my husdband on march 18. My last period was on march 8. I'm very regular on my cycle and still today I have not got my period. I feel exhausted, eating a loooot, fatige, etc. We did the pregnancy blood test and it came out negative but when we did the test i only was like a day late on my period. When is the right time to repeat the blood test?
P.S. Sorry for my bad inglish. I'm spanish.
