My last period was the 16 March, although it didnt really start properly until the 17th. I had unprotected sex 1st/2nd/3rd April. Does anyone know if thats my fertile time? Im trying to work it out?! and yes, trying to get pg!
as a general rule i think its 13-16 days after first day of period.
If trying then perhaps you should try throughout the month as it does vary. Try not to put too much pressure on yourselves by setting dates and times as the stress can prevent pregnancy too.
