Late period

Ok so my cycle is about 3 days late right now. About 10days dpo i took a prego test and it was negative but after sitting overnight it changed to a faint positive. So i took 3 test after that and they were all negative. Well about 1 day before my period i took another and it still came negative. Now my period is actually 3 days late....no sign of AF at all. Cervix is high and kinda soft...i cant really tell the difference right now. It seems closed, idk. Anywhooo I'm scared to waste more money on a prego test and then it come on. Last month my period was 8 days late and finally came on so i figured this time I'll wait past the 8 days, maybe til like next friday or saturday so it'll be a good 2 weeks late and then test again. What do you all think?! Help please! **if i am, this would be my 2nd child. I dont really remember my symptoms with my daughter except her dad was always sleeping and i got a bfp the day OF my missed period**
