strange symptoms

Annabel
Hello ladies, I'm just wondering if any of you have had the following symptoms during the time between ovulation and AF
Period cramps 
Constipation 
Very mild lower back pain 
Myself & my partner have only been ttc for 2 months. I have been off the mini pill for around 3-4 months. 
Also I eat a lot of mayonnaise and today during my lunch break I could only eat a minimual amount and had to spit out the food I had in my Mouth out sorry a little TMI. 
My SO is starting to think I might actually be pregnant I'm not as hopeful as he is. 
If any of you lovely ladies are experience this can you please help me not to over think things. 
Baby dust to all the ladies currently in the ovulation phase may your eggs and sperm be fertile. 
Thanks 
Annabel
