My last period was on the 25th of last month and was lighter than usual. Not long after that (about8 days) I started to feel as if I was ovulating, if it was ovulating, I have been having lower and upper back pain since then. There are two times where I can see where I MIGHT have gotten pregnant: a month ago(april 12th) precisely or just a week and a half ago (May 8th).

-Breasts hurt
-Heartburn
-peeing 7-10 times a day
-backpain, upper and lower
-Stomach pain

For the past three days I have had a temperature of 98.9-100.0

I took an EPT today and I got a positive. Well the vertical line was solid blue but the horizontal was a faint blue....pssible pregnancy?
Help, please
