Symptoms but just got AF


My husband and i have been trying for 3 months and this month i really thought it was good news!

I have had sore get off dont touch them sore. And i fall asleep in the middle of the day and im so tired. I have felt nauseous for 2 weeks now and certain smells make me want to be sick. I was trying not to get too excited.

And today i was crushed. I woke up in agony to the worst period cramps ever. And when i went to the toilet AF had defo appeared! I am devasted.

Am i just going crazy? Why would i have all these symptoms and yet not be pregnant? I get no symptoms in the lead up to period week. Im so disappointed.
