4 weeks 3 days

I found out that I'm pregnant on Monday. I couldn't believe it since my husband and I have been trying for 5 years with 1 miscarriage. I waited for Wednesday for period because I couldn't believe what I was seeing on the tests. I haven't gotten my period and all my home pregnancy tests say positive. I'm scared and nervous and confused. I don't want to get excited because I don't want the doctor to tell me that I'm actually not pregnant or to lose my baby. I feel so guilty feeling this way. I want to be excited but my mind just doesn't feel that way.
