Pre-pregnancy test early symptoms

Emily • Wife, mom, and ttc baby #2.

So I know it’s just a lot of wishful thinking but I’ve read a stuffy nose with heavy mucus can be a sign of pregnancy only 7 days after ovulation and it’s 6 days for me right now. My husband and I had sex the day before I ovulated, and yesterday I could feel a sore throat coming on, then today out of nowhere my nose got all stuffed up and I’ve got this bad cold. I was wondering if anyone else has ever experienced this as a symptom of pregnancy before they were able to take a test? Like I said, I’m really hoping I am but this cold also came out of nowhere.
