symptoms and tests

how long after you think you actually fell pregnant did you manage to get your test back positive and how long did it take you to start noticing you where feeling out of sorts . if I have my dates right .. I'd of had my first faint pos exactly 2 weeks after intercourse .. and was feeling slightly out of sorts for a week before that. Couldn't stay awake constantly nauseous . stomach cramps... I didn't think it was possible for me to fall as I've had a high number of miscarriages and never succeeded in falling pregnant for just over 3 year so when I felt out of sorts , I went to th Dr's after a week of it she booked me for a smear , after she got negative pregnancy test results. that was on the Friday . Anyway the weekend passed on the Monday .. just because I had one in th medicine cabinet .. I took a test myself . Monday been exactly 2 weeks from suspected conception .. and got my positive . Thought in he insight . surly it wasn't right that I should of been feeling that I'll only a week after conception. But had negative tests all that week so couldn't be that I'm further than we think. What's your experiences with testing a symptoms ?
