I'm tired of waiting every single period for the miracle to happen..this month I have been in so much pain ..I had food poisoning keeped vomiting in early morning that happened 2 days after ovulation ..I have been having headaches since my last period ended .. back pain the never stop.. mood swinging .. pain in my both sides ..I having pain in my Vagina and the area beneath my belly button. I had constipation for 3 days . I'm just sad and angry and wish that i could be pregnant this month my period is in 2 days .
