Sharp pains ttc#

ttc for rainbow baby • My husband and I have been together 7 years. Married since Aug 2014. We started ttc in July 15 and got pregnant first month and it ended in an ectopic. We are now waiting for our rainbow baby .
Today is the day I am to start my oeriid. I had to go to bed early last night because I kept having sharp pains all over my stomach. I woke up again at 230 with them todsy. They don't feel like period cramps and it's almost hard to breath with them. I have had several other symptoms lately nausea; my feel bigger and cramps 9,10,and 11dpo. Is it normal for sharp pains stomach aches while your pregnant? I have a strong feeling that I am. I can barely take 5his pain any longer though
