Anyone experience anything similar?

This whole month has just been crazy off. Stick with me here and please dont just say "take a test." Yes, I know take a test, I'm going to, but I'm wanting to know if anyone else has experienced something similar and did/did not end up pregnant. First, I got spotting the second week of my cycle. Then it stopped. I got a temperature of 99.4F. Then I got sick (throwing up for about 24 hours) and then I got what seemed like a period for the 3rd week. Now that "period" is ending and my temp is still sitting at 99.4F. I've always had 28 day cycles with no spotting in the middle. So this is VERY confusing to me. I've also got sore boobs and a stuffed nose. My emotions have been all over the place. I'm bloated, have heartburn, and constipated. I don't get it. I thought it WAS for sure pregnancy with the weird spotting happening. Then got what seemed like a period and I was sure I WASN'T pregnant. Now idk what to think because this cycle has been all over the place and that's not normal for me. Plus with all the "symptoms." It is unusual. I don't know what to think. I'm so scared to test and also unsure if it would even be accurate because I was expected to get my period this upcoming thursday (Thanksgiving) and it's only Sunday but I already had what seemed like my period and it just ended today. Anyone have any ideas?? Experience anything similar and were/weren't pregnant? When should I test? Now or when I was expecting to get a period until I already bled?
