How I knew I was prego?

I have been pregnant 4 times that I know of, and each time I just knew I was pregnant. My breasts were different and felt heavier and hurt on the sides and my nipples hurt also. That was my first sign and it was usually a week after I ovulated when implantation must have occurred. I guess you could say intuition also told me something just felt off. I had spotting with my first pregnancy, with the sore boobs and raised BBT at the time my period was due, so I took a test and of course it was positive. The BBT is definitely accurate for knowing if you are pregnant. It absolutely will stay much higher than usual. For me my normal temp is 96.8 ish before ovulation and after it usually spikes to 97.7 to 98.1. When pregnant, each time, it has been 98.4 ish and stayed there. Unfortunately, none of my pregnancies made it though, so I am now giving up on trying anymore.
