i bought a clear blue easy digital pregnancy test, both showed up "not pregnant", but i still think maybe i am. ive had sharp pains here and there in the bottom right of my abdomen.
so, do ectopic pregnancies have regular symptoms and do they show up on a test?

YES an ectopic pregnancy would have increased hcg levels that would give a positive reading on an HPT

My wife and I started trying to get pregnant 5 days ago. According to ovulation web sites we stated on the best day possible. Yestersay she complained about achy leggs and feeling "weird." Also mild cramps. Are there symptoms for pregnancy that occur so quickly?

not really, early pregnancy signs include sore aching boobs, fatigue, nausea, vomiting and all these signs usually occur about 1 week before period is due.
