Tbh hun..its a tad early to be getting a bfp at 6dpo.
The egg doesn't usually implant until 6/7dpo. I had spotting at 5dpo and actually dismissed it as implantation bleeding cos figured it was far too early.
So if it did implant at 6dpo it'll take a few days for the hormones to build up in your system for any type of symptom or result.
I too have been getting the back ache and twingies low down for about a week post ov.
Don't get me wrong I really hope you get a 'ickle sticky bean - I really do. I just don't want to build your hopes up into believing that your symptoms are pg related when in my honest opinion I think its a tad early. Sorry hun.
Am wishing you all the luck though..lets hope we both get a sticky bean
Ps - did you not have a ttc ticker before?
I'm sure there's a ticker missing of your signature
