Confused

2 weeks ago:

I thought I had implantation bleeding when I went to the restroom. The next time I went to the restroom... no bleeding, but there was a creamy/cloudy white mucus like substance. Then like two days later, i had a little spotting. Everytime I go to the restroom there is always the creamy/cloudy mucus like substance. Also, after intercourse, my SO stated there was a little blood on his penis, so we assumed AF was coming.

Last week:

So, I assumed I was pregnant. I was(am still)having pregnancy symptoms like food and headaches etc. I kept having the mucus like substance everytime I went to the restroom so I took a pregnancy test and it was negative.

This week:

According to Glow, AF was suppose to come on the 1st. It instead came on the 3rd 😡😢😈 Sooooo, after all that.. my question is...

Can you be pregnant and still have a cycle? Like one last cycle?
