I usually have my period every 4 weeks. But it's been a few days past 5 weeks and still nothing. I've been feeling nauseated, like everything makes me feel sick to my stomach. I can barely sleep cause I feel so sick and then I wake up feeling the same and it'll go away for a while then comes right back. My breasts have enlarged, which always happens before my period but they go back to normal size after a couple days and they've been like this for 2 weeks. I did think I started my period, there was a very faint amount of blood but then there was nothing after that. And I'm tired all the time and I didn't feel bloated until just today. I'm just wondering if anyone thinks I really could be pregnant or if it could be more likely all part of my period and that it's just late??
