[amy]

as i said me and my husband have been having unprotected sex for 14 months now and i am still now pregnant? why is this? Also i have thought i was pregnant a few times so i took a test and it came back that i am not pregnant but i am confused because i have had so many signs that i am, am i just thinking i am having signs because i really want to be pregnant? i would be so gratefully if anyone could give me answers as i am getting so upset over it all my friends seem to be able to get pregnant and i cant i don't feel like a women. thank-you x
