Curious about these symptoms!

Hi glow! I am 21 and I have been married for about 8 months now and since we got married we decided to TTC. Well the first period I had after we were married came at a month and a half which is not normal for me I am very regular! But anyways I got used to this cycle and went with it but here it is November 15 and my last period was September 20th. I have cramping like I am on my period but they come and go and no bleeding, I have mood swings, am gassy all the time and I am eating everything in the house. Also I am very tired but not sleeping all the time and let's not forget frequently peeing. So my question is how should I translate these symptoms? Is it baby or AF or maybe just my brain?
