Opinions please💛

I will be testing this weekend, but just wanted a few opinions. I have pcos so I'm not sure when I ovulate but my pass 4 periods have been on time with each other and everything is fine but now I am 15 days 'late'. I wanted to wait to get an accurate result since I'm not sure what my 'late' really is. Symptoms so far. Mood swings, emotional, sore throat, headaches, cramping but not painful more of a dull ache but I can definitely tell it's there, nausea (no vomiting), I feel like my blood sugar is low like if I don't eat something every 2.5-3 hours I am dizzy and feel light headed. I am usually a bored 'snacker' so I don't ever feel hungry or have a growling stomach but the past week I would say I am physically HUNGRY often. and last weekend I was constipated one day, diarrhea the next then constipated again? Is any of this normal for this point in pregnancy if I am pregnant? * no sore breasts, but they are itchy I would be about 5 weeks
