Hi everyone, i'm 20 and I just realized I was late. 15 days late. All of the signs for pregnancy were there but I was wanting to wait another week for a blood test, but I started what seems like my period, the only problem is my period is way heavier than usual and I woke up this morning with piercing cramps. The cramps lasted about 2 hours which made me nervous because for one my period hasn't been heavy since I was about 16 and i've never had cramps, I'm really scared it could be a miscarriage. Has anyone experienced this before, or are my fears valid. I'm sorry I'm realy naive to this, I've never had a child or even been pregnant. Please help, your input will help ease my mind.
