Pregnancy can happen when a sperm meets and fertilizes an ovum.
While sperms are released at every act of sex...the release of ovum is not known to women as there are NO symptoms
The ovum has lifespan of 24-48 hrs so sex has to be planned not to miss the ovulation window
So most couples try by the fertile period (FP)
As per your dates your period cycle appears to be 32-33 days
To calculate FP, estimate your coming menses...say by 23 june...
Now count 14 day back...i.e 9/6....
Have sex on 3 days on either side of this date i.e from 6/6 to 12/6
this is fertile period
Try this for few months...if you dont succeed or have passed 1 yr trying to be pregnant it would be better to seen gynecologists consultation.
