Is this a legit early pregnancy sign???

S

So every month I feel like I am paranoid I am pregnant since I’m not on birth control and my bf and I have sex almost every day. We try to avoid ovulation days and use pull out method as our form of BC since I react poorly to most other forms. This month we did have sex the day before ovulation and the day it started using pull out. Basically, I had taken 5 days off for my birthday which is tomorrow and 4 of these 5 days I have been in bed with allergy/cold like symptoms, fatigue, and nausea. Although I can usually talk myself down about being pregnant- once I read that sneezing/allergy like symptoms could be a very early pregnancy sign I’m trippin because it is not the sign for seasonal allergies and I have sneezed SO many times today, itchy eyes and throat, and the grossest taste in my mouth. My throat is progressively getting better but the sneezing has not it has been about 3 days of this. My period is due in 6 days so the fact that my breasts are SO sore wouldn’t normally cause me to be suspicious, but combined with the sneezing, congestion, fatigue, and nausea I’m a little worried. Is it too early for a test or too early to have these types of symptoms?? I haven’t fully thrown up but yesterday I gagged 6 times and today I did have to run to the bathroom and threw up a tiny bit.
