Chances of being pregnant?

Melissa
I typically have 30 day cycles, today is cd 44. Have had 2 negative hpt on cd 39 and negative blood test on cd 40. For the past 10 months I've had a vegan diet, so no meat, dairy or eggs for 10 months! Just 3 weeks ago I started craving pizza and ice cream and food with dairy in it, so on August 6th I decided to give in to those cravings and started being vegetarian. My fertile window was July 28-August 2. We BD every other night bc we're TTC. Since going vegetarian, I've had some gas, bloating, constipation and diarrhea. Sorry TMI! My question is...do you think the hormones from the dairy has caused my period to be two weeks late or do you think there is a possibility that I could actually still be pregnant and just not have enough hcg yet??? Please respond!!! I need help and guidance and advice! I'm losing my mind here!!! Thank you in advance for reading this❤️
