Scared to test

So DF & I have been TTC since October with two times thinking that I was PG but unfortunately I wasn't. AF showed up 4/25, was due again around 5/25 and here it is 6/5 with no AF. I'm cd41, having lower back pains, lower abdominal pains(alittle stronger than cramps), ariolas seem alittle darker, breasts a little more sensitive. I really want to take a hpt but afraid of disappointment.  Need some advice but really just needed to vent
