Trying for 2nd

Here’s my clue app. All the green squares are when my husband and I had sex. That dark blue I had some severe cramping, which is unusual to me to have cramping 2 weeks before my period. My period is always consistent, it’s due in 4 days.

I took a test 2 days ago because of the cramping and I know that’s really early to take a test and it came back negative. I have 2 more but I’m waiting to test again until closer to my period to see if I missed. How accurate would it be to take the test now, 4 days before my period?

Add: I’ve been urinating frequently. I woke up one night 3 times to pee and still having cramping

When we had our daughter we were trying, then when we stopped trying so hard lol I got pregnant. I get so anxious and obsess over wether I’m pregnant or not.😫
