I had sex on my first fertile day then four days later after that on another fertile day about 2weeks ago, well today I Had mild cramps off and on for half of day then it stop, period not due until 3days, I don't have any STDs got a pap did on the 6th, everything came back normal... I been trying to conceive so I wondering is that a sign of pregnancy or early cramping before cycle?? which I never get (when I do start to
Have mild cramping it's the day of my cycle and I start a few hours after cramping start)

Cramping is a sign of PMS, but can also be a sign of pregnancy. Sadly it's not a sign that would lead anyone to say that you're definitely pregnant. PMS and pregnancy symptoms are almost exact.

Wait until your period is due. If you miss it wait a week and then try a pregnancy test using first morning urine.

I know it's hard when you're trying to conceive, every little hiccup can be construed as a pregnancy symptom, but really, this is one of those things that can be either or, and not a definite sign.

Good luck. :)
