Is low pelvic pain a symptom of pregnancy or AF coming? I hate how the symptoms are so similar and I get all pregnancy symptoms and then AF shows up.

Is it normal right after ovulation like 2 days after you feel period cramps? I had very intense period cramps and I was so cranky. AF is supposed to show up in four days and I don’t think this month is my month 😣 my boobs arent sore the only symptoms that I am feeling are cramps, so cranky, and fatigue.
