It's hard to track my af because I just got off of birth control in April of this year. I have been on it for 3 years! August 14th and 15th I guess you can say was my period. I bled but nothing major. So glow gave me the estimated ovulation window and me and my husband had sex every night during that time .... I had spotting (only when I wiped one time) on August 3rd ... My af is due in 5 days ... but the past 2 days I've experienced dizziness, headache, feel like I'm going to throw up but never do, tiredness/ exhausted, cramping and diarrhea could I be pregnant?
