Okay so i really need some help. me and my husband have been trying really hard for a baby. I got my period on January 17, it is now March 13 and i still havent gotten my period. we had sex on my most fertile days. I have taken a few pregnancy tests but they have said negative. We are thinking that i was pregnant once and lost it too soon to tell which is why i missed my period in February and we think that now i am pregnant but too early to tell.... i have been having pregnancy symptoms like missing my period headaches back pains nauseous in the morning mood swings very hungrt and extremely tired. i was pregnant last summer but lost it at about 14 weeks. we are now trying again and really are hoping for some answers. please help.
