Has anyone missed a period, but had a negative pregnancy test?

I’ve been intimate with my partner a month ago; around my fertility window. I recall having what I believed to be my period on October 29th, but it was light and lasted for only 2-3 days when my cycles are typically heavier and last longer.

A few weeks later, I began to feel really crazy pregnancy symptoms such as food aversions (dislike towards my favorite foods), cravings I haven’t normally had before, stomach tightness and abdominal pain, and other pregnancy symptoms I don’t want to disclose as they’re personal and tmi, even though it’s normal in pregnancy.

I also began to get a cold, and my immune system is typically very strong and I haven’t gotten sick in nearly two years. I did my research and found that pregnancy can weaken the immune system.

I used Ovia, which is an app that tracks when your next cycle is expected. It was expected on the 29th of this month, but it is now December 6th and my cycle still hasn’t arrived. I’m a little nervous, but I haven’t felt many pregnancy symptoms lately and I have already gotten two negatives. Should I just accept that I got a negative result and be done with it, or should I wait a few more days and test again or visit the doctor for a blood test to confirm? Has this happened to anyone?

Thanks to anyone who helps 💕
