I've had two previous miscarriages June 4th 2014 and May 21st 2015. Thought I may be pregnant however have had multiple Negative tests even FRER curved ones. I was supposed to start period July 22nd so I'm 5 days late. Period only lasts 3 days when I get them. Whole cycle is 28-32 days. Really confused as my last two pregnancies I found out on day of period and 4 days before period. Not really sure if I should just give up on testing? Or just keep waiting to see if cycle comes? Or just call my dr? Just don't want another heartbreak. During this time I've had real strong pregnancy symptoms : nausea, fatigue, craving and increase appetite, bloating, gas, heartburn, and dizzy. I'll be 24 yrs old in Sept.
