Hi, I'm really desperate for some advice or thoughts please. My cycle is normally 27 days and my husband and I had unprotected sex on day 9. Roughly 5 days after that I had lower left abdominal cramps and back pain that lasted a day and a half. Since then I've been fatigued, bloated, had mood swings, feeling faint. Does this sound like it could be conception related? These aren't usually symptoms I'd get with ovulation. How early can I take a test? I'm on day 17 of my cycle now. I've had a look on Google and it says it would be too soon for symptoms so maybe I just have an illness?
