IMPLANTATION??? Need help !

Hello there. I'm hoping someone experienced this and was actually prregnant.

My period comes every 24 days. My partner and I had sex on my 1st  & 2nd fertile days.

My period came 4 days late and was extremely light and lasted on 3 days which isn't normal for me. I soak a pad every hour...sorry if it's TMI.

After 3 days of light bleeding I spotted for two weeks straight and then my period came an entire week early and was light again and only lasted 2 days.

I'm REALLY confused at this point. My systoms have been dizziness, bad gas, some light cramping and headaches.

According to my calender I would be around 6 weeks if conception took place on June 21st. I'm basically wanting to know if any ladies out there spotted and had  light bleeding for an entire month then found out they were expecting. Thanks so much for any responses xoxo
