I am so confused. I am a week late starting my period, but I have taken 3 pregnancy tests and theyre negative. I have had all the minor symptoms of pregnancy, but the urine test continues to be negative. I have had low HCG levels in my previous pregnancies, causing tests to come back negative or 'inconclusive'. Am I just stressing myself out so my period hasn't started? Is it possible that im not pregnant even tho my period is so late? Is it possile I am pregnant even tho my test said no? If I am pregnant, will I miscarry because my HCG levels are still so low?

Someone please help me and give me some peice of mind.

I have had 2 live births and 3 miscarriages. I am a single mom, and just need to know...
