Could i be pregnant or is something else?

So this might be a long lost but so for last few weeks my body has been very weird. The last time i had unprotected sex was the 2 of the month which was also the first day of my ovulation. And then i got my period on the 16th. Which normally they come 4 days early and never on the app says but anyways last like 3 maybe four days at most and it’s was pretty light and they normally last a full seven days and then yesterday i got it again but it’s still very light. But before i got my period i had been having a lot to pregnancy symptoms like i did with i was pregnant before in October but i lost the baby. I’ve been extremely tired, nauseous, very sensitive to smells, a lot of discharge and my feet have been sweating a lot and things would taste weird when i would eat but now it’s like really bad tasting and i know it’s nothing with my dental hygiene because i always take care of my teeth like idk how to explain the taste but it’s just gross. Some stuff i can still eat and be fine will with but not a lot
