Missed period...

I have long cycles of between 41 & 47. I am now on 57 so a good 7-10 days late on my period. I think I ovulated on CD 36 and implantation occurred after, as I had tugging pain on one side of my stomach.

Ever since then I have had so many symptoms of pregnancy that I thought I would have had a positive test by now. I last took a test on Thursday, CD 53 (CB digital) and it was negative, but may have diluted the test as the wait sign started before the 5 seconds of peeing on the strip.

What do you girls think? My symptoms:

1) sensitive to cigarette smoke

2) going for a wee often

3) boobs are larger

4) nipples are sore

5) bloating

6) Indigestion (don't normally have this)

Do you reckon to take another CB test, to buy a FRER or go to the doctors to get a blood test done? I need advice!
