I need some help please

So I’ve had a faint positive test two days ago, and today a faint positive but darker then the one before 2 days prior. Was laid in bed this morning when I read the pregnancy test and excitedly told my boyfriend who proceeded to look at the test and say “no your not, the line isn’t dark enough, it has to be really red” I explained it doesn’t and that sometimes when your early on you’ll only get a faint line. He then said until he sees a test that’s really dark, it’s not positive. I’m obviously excited we are going to have a baby, and we are TTC so its not a total shock. However it is our first month of trying - my question is. I’m not going to tell anyone else I’m pregnant until the first scan, however it’s ok to say when I’m around my partner I’m pregnant with this test, wouldn’t you think?

Also I’m experiencing period pains as I was supposed to start three days ago, I also have very sensitive nipples. With regards to period pains, is this normal or is it a sing I’m loosing the baby?

Added a picture of this mornings test :)
