Some women do feel symptoms of pregnancy very early on. I would take a test.
when was your last period and when do you expect your next and how long have you felt this way?
Also I just dont feel like myself. Im always tired and my legs hurt. I feel bloated and full all the time even when I dont eat. I dont know. I know the pain in my legs are not due to lack of water because i drink about 60 oz a day. my breast hurt a little and they feel like they are getting a little bigger.
