My body is feeling really weird HELP

I'm in a weird situation full of uncertainty.
I don't really know what to do either since it's too early for a test.
I stopped the pill at the end of last July and my periods have been very irregular.
First 25 days, then 2x 28 days, and then about 2x 31 days.
Those were roughly the cycles I've had over the past few months.
Now, I had sex on April 16 and April 20, and the first day of my last period was April 5, with light bleeding on April 3 (spotting).
The thing is, since April 22 I've been having sore nipples and the feeling that my period is about to start.
This feeling makes me feel very unsure because I really want it to be a pregnancy, but I'm also afraid that it isn't. Normally, I feel these cramps 7 to 5 days before my period starts. But now they've started a few days earlier, which doesn't fit my usual rhythm at all.
I don't understand any of this and it's making me so anxious because it's too early to take a test.
I'm so worried that it's nothing that I'm finding these days hard to get through due to the stress.
This baby is really wanted, so maybe you guys have some feedback for me.
