Pregnant??

Hubby and i have been trying for baby #2 since November and it's been a tough time. I started not having periods and having false positives in feb.. and I believe I had a miscarriage in march.. past two months I've had a very light period but hey I had them. but I was suppose to start on Thursday and nothing yet.. my breast have been tender and sore to touch today had some light cramping but no bleeding and I've been hungry but go to eat and don't want to finish eating. Thinking about testing tomorrow or monday. I just don't want to get my hopes up again and not be..?
