Hi, so I think I might be pregant but I'm noy sure. If I did concieve it would have been about 2-3 weeks ago. Ive been having a lot of early pregnancy symptoms including the fact that my breasts have gone up almost a whole cup size. Ive taken 3 tests and they all say negative. My period usually starts around the 18th-20th but I have none of my normal signs of pms. Has anyone ever gone through something similar?
