🌸🌸🌸Any advice please????🌸🌸🌸

Glow is telling me that my cycle is 31 days. As of now I’m 4 days late but I took a pregnancy test last Sunday and it was negative. I feel weird little pains in my ovaries and It feels like my period is going to come soon but nothing yet. Did anyone conceive with a irregular period? I notice my cm isn’t fertile like so I’m just kinda going baby crazy . Should I wait a couple more days? I’ve had 3 chemical pregnancies and I’m scared that my body recognize it. My hormones are also imbalanced so I’m having a hard time ttc.
