started charting this month so being a bit of a dumbo...but had a massive rise this morning +1c what does this mean? According to my calculations, Ipod Period Tracker, FF I am not due to ovulate until Friday so what does it mean? Do I in fact ovulate earlier than expected? Did an OPK and no line yesterday....no line at 10am but will try throughout the day Unfortunately I have been signed off work with a virus for 1 week and so BD'ing is very unlikely as hubby is feeeling pretty under the weather too typical first month of charting!!
