I m 38. I was diagnosed with HTN. My last LMP was on July 25. I was 7 days late making it 37 days since my previous period. While waiting on my cycle to arrive I experienced sore nipples . I m sleeply (but I work a lot and also in school, so it s more sleep deprivation ), I have occasional slight cramping, occasionally feel sick to my stomach ( nausea ), had a headache this morning. I ve taken 2 HPT and both were negative. I m trying to determine if I am peri-menopausal or pregnant.
