Since you are trying, then sure, you could be pregnant. Symptoms aren't a great way to know though Since you are late, why not take another test in a week? For the future, you can take your temperature which helps you know what is going on with your body. Our temp raises about a degree around ovulation and stays that degree higher until we start our next period. Unless we are pregnant and then it never goes back down. My temp stayed high two times, with both of my pregnancies! You take first thing in the morning and chart it. Sorry for your miscarriage. Let us know if this was your cycle
