need advice 😂💖

okay everyone i just want to explain what ive been experiencing and i want to see everyones prespective of this is normal. okay so i ended my period on the 18th of August, as soon as it ended me and my boyfriend had intercourse even leading to the days that i was suposed to ovulate. but on the beginning of my ovulation after we did it,i started to bleed. it was light at first but then it started to go just a little heavy. i also started to experience cramping and so fourth. so that lasted 4 days! then it stopped, now i feel so exhausted all the time, im hungry alot more, i experience some cramping but thats about it,not to mention i feel nauseous more. so i thought i should take a pregnancy test,i went off on this app but i also have its partner app eve,which has been more accurate then this one(not in a bad way lol) but it came out negative(i used the early test)should i just wait to see if i start here in the next 4 days or just assume im going to get my period cause im feeling crampy?? advice?
