Hi Everyone

My husband and I have been trying to conceive we had sex the beginning of December during one of my ovulation days and I received my period on December 18. Because I received my period I assumed I was not pregnant. Now its January 24 and I was supposed to get my period January 19. During the week of the 19 I was spotting a brownish color but I'm no longer spotting anymore. My periods normally start right on time or a few days before, but now I'm late and not sure what to think.

Can anyone offer any insight?
