What ya think?

Ok I haven't had a period since August 1st me and my husband believe it's pregnancy but I took a test today and it was negitave, to early maybe? my boobs hurt like hell! slight nausea, heartburn, cramps, really moody and a really weird one i smell sperm, I know it's not like old sperm or anything I just smell it on me idk how else to explain it like I smell like my husband! It's insanely weird. I have heard people say you smell sperm when you are pregnant with a boy, idk if that is true or not though. my first child was a girl so I wouldn't know. anyway, any thoughts would be great!
