My cycle hasn't been regular since before my first pregnancy. I have been overly stressed as well as depressed lately. I had sex twice on August 8th and was also at the end of my cycle. Today August 12th, I have felt nauseas all day, and keep getting dizzy whenever I stand up or move to fast. I also have really bad heartburn and I have been burping all day. Is it even possible that I could be pregnant or is it just from being depressed and stressed out? Please help! I already feel bad emotionally, I can't handle feeling bad physically too! Thank you for your time.

It would be too early for you to be experiencing pregnancy symptoms.
