Feeling ick! Pregnant?

Alicia
Okay...so...the past week or so I have just been feeling drag. Completely week. I have continued my normal workout routine. I had my implanon taken out about 1 year ago and my cycle is all out of wack. So I'm not sure if I could be pregnant. I feel sick. No fever. My cycles have been like 50 or longer days. Haven't taken a test yet. My husband thinks I'm crazy. Please HELP!
