I had a bit of a metallic taste in my mouth and extra saliva in my mouth.
I also ate some Mersey Valley cheese with pickled onion in it which I usually love and it tasted gross. My breasts felt larger. My sense of smell was also a bit more sensitive. I was also coming home from work really hungry in the afternoons.
Those were the symptoms I felt before getting my positive pregnancy test. I was really lucky and fell pregnant in our 1st month of trying. I didn't think it would happen that quickly so I thought I was imagining the symptoms because I wanted it to happen.
