22 with PCOS but think I may be pregnant

Hi everyone,

I'm new here & I'm not sure what group to post in so, I've posted it in 3 different groups ( sorry). Nonetheless, over the past month I've been experiencing so much fatigue, back pain,female area cramping, nausea, etc. My period was almost a week late as well. However, I took a test that came out negative. Then my period came on the 10th of this month it was about 5 days long (which is a lil shorter than usual)....BUT, I did recently have sex during my fertile window & ON the day I was expecting to ovulate ( the 27th of this month...three days ago). All of my doctors I've seen recently and my mom keep bringing up the topic of me having a baby for some reason. Which is also like a sign of the future to me. Should I just chalk it up to being my hormones? Or should I continue to be mindful of these random symptoms?

Thank you❤
