Sorry - this is a long post.

I'm a little bit hestitant to say, but I think I have recorded a BFP!!

I started charting mid-way through my cycle, using a normal thermometer and testing a bit adhoc - FF shows I am currently 9dpo. I think the most likely BD date to cause conception was 17th March (3 days prior to FF O date).

On FF calculations I tested 7 dpo with Confirm- (addict - couldn't help myself!) and got an ever so pale, use your imagination, second line. Tested yesterday at 8dpo and got pale line again (Confirm). So bought some different brands and tested in the afternoon. Discover Onestep can up as a lighter but definite second line, within 3 minutes. Fortel came up with a 'use your imagination' line, and I tested an hour later with Discover and second line came up very clearly (although lighter) within the 3 minutes.

I tested this morning - 9dpo with Discover and got the same second line, and also Fortel and got an every so pale 'use your imagination' line again.

So - pretty much every test I am doing is coming up as a BFP in some form. I am surprised I am getting a second line at 9dpo - (or earlier in fact) - so am wondering whether I may have O'd earlier. Would it be possible that I ovulated on or just after 17th March - same day as BD - thereby making me around 11 or 12 dpo? (FF showed I o'd on 20 March).

I am new to charting, but didn't really pick up an fertility signs - before or after this date. Only thing was had a OPK surge (although not positive) on the 17th, then surges a few days later around the time FF showed I O'd. (again not positive)

With all my tests revealing something, I think I am probably preganant - but trying not to get my hopes up too high.

Given my uncertainty about O date, is it too early to go to Doctor for a blood test? Should I wait until when I think my period should be due (either in a 2 days at a minimum or 5 days time).
