is it possible to ovulate early

here it goes. every month I get ovulation pains from the start of ovulation to the end so it's pretty good for me to tell when I'm ovulating anyway this month I haven't had any cramps due to ovulation I had high sex drive 3 days before glow app announced my fertile week. so we baby danced for 4 days each night. legs up afterwards lol

the last week I have been getting alot of symptoms like really tired badly id sleep all day and night and for me that's not normal lol. my back had been killing me the pain is unreal and also my boobs every morning are feeling like rock. but through out the day they feel heavy and ache. Iv been feeling sick my amazing morning coffee has turned into fruit juice cause I cannot stand the taste off coffee. I'm craving sweet food and usually I don't. me & my husband been trying for almost 2 years for baby #3 my period is due 5/9/2017 so it's well to early to test but I'm finding it hard to keep my mind busy and not on pregnancy. anyone have anything like this that can help?
