Hi guys. My husband and I are just starting to actually try but haven't used any protection in years. 
Well my last period was 45 days Ago. I have been slightly nauseous, my breasts have been extremely sore, I constantly feel like I have to pee, slightly crampy, and really tired. (The only usual pms symptoms I have out
If these is being tired)
I've done the pregnancy tests so many times because I have been late so I'm just not sure when to test because I'm not completely regular. 
Any advice.
