Today is July 5. I had my last period on June 10 and my periods are regular at 26 days. I track my basal body temperature and calculated my ovulation by the rise in temperature and ovulation cramps. During this time I had multiple acts of unprotected sex and I'm on no birth control. Normally, my temperature remains pretty steady, but on June 28, about a week after I ovulated, my temperature dropped and a few days after that it rised higher than usual. It has dropped since then, but remains higher than usual still. Along with this, my cervical mucus has unusually increased when I normally have very little until after my next period. For the last 3 days I've been feeling very, very mild cramps that are not consistent. The day of my period, my cramps are not severe, but are stronger. Yesterday, I noticed I was spotting. It was very, very tiny amount and it was just that one time. When my period starts it's more than just a tiny amount and continues and not stop on it's on. I took a pregnancy and it came out negative. My period is due tomorrow and maybe I should had waited about a week after implantation if this is implantation symptoms. Is it more likely I am pregnant?

If I were you, I'd wait a week and take another test. Many pregnancy symptoms are the same as menstruation symptoms, so it's difficult to tell.

What I remember most notably is going up a cup size within the first month of pregnancy.
