Anyone else have this happen?

I'm trying to concieve my second child. I had sex on my fertile day almost a month ago I was 3 days late for my period at the end of July now with my first child I got one last period before it stopped and it was a weird period it would only last 2 or 3 days. So in July I was suppose to get it on the 23 of July but got it on the 26th it only lasted 3 days but it was an odd period where I was only spotting when I wiped there was no blood clots but I had discharge while on my period which was weird. So after my period ended I started getting symptoms of being pregnant. I'm starting to feel more tired. I'm getting sick, certain foods don't taste good to me or I can't finish eating them. My urine is cloudy, but I took 2 pregnancy test one was defective and the second one was negative. Am I pregnant but it might to early to tell or is my body acting weird
