Could I be pregnant ?

My husband and I have been trying to convince and my period was supposed to come 4 days ago and I still have not gotten it yet. My cervix is high up and closed and is usually low and open when I’m about to get my period. I have been bloated, emotional/moody, have slight cramps that I almost don’t notice sometimes and my nipples have been slightly sore. I have all of these symptoms before my period is about to start except my cramps are usually worse but I know these can be symptoms of getting your period as well. I took a pregnancy test when I was 2 days late (I know that’s kind of early but I’m impatient lol) and it was negative. Could I be pregnant and it’s just too early to test? My period being 4 days late and my cervix being so high and closed is kind of throwing me off because like I said it’s usually much lower and open. I do have irregular periods at times but for the past 3-4 months, maybe even longer, my period hasn’t been late at all.
