What are my chances ?

Brianna

Had my period September 8-13 ovulated the 22 and this month wasn't a good month trying to conceive unfortunately we only have sex the day I ovulated9/22. My period is due 10/7 my boobs are sore and I felt super nauseous at work today and I have cramping in my lower back. I highly doubt I'm pregnant but what do u guys think. Is there a possibility or am I just expecting Mother Nature?
