Earliest Pregnancy Symptoms

All you mommas out there, how soon did you start having symptoms and what were they?

I am TTC and irregular but at my transvaginal ultrasound the doctor said I had a perfectly good egg and we tried several times, so there's a possibility I could be pregnant. I am feeling bloated like crazy and my nipples are so sensitive I can barely touch them. My gums are also bleeding very easily. Could be AF symptoms, could be a baby. If AF shows up I am going to start clomid to hopefully get pregnant. :)
