Ideally if you have a 33 day cycle you may ovulate around cd19.since you dont have same cycle each month i would start tests cd17 onwards.i would say sex every other day is ideal,however main time is during ovulation.sperm can stay in the vagina area for up to 5 days.try having sex as much as you can from cd17.ovulation will generally occur 14 days before your next period.make sure you use test after holding your wee for at least 3-4 hours.and test same time each day.ideally early afternoon.it would also help if you charted your temps,as tests will only tell you you are going to ovulate.where the charting will confirm O.best of luck.
We can't try everyday see he is in the ARMY some nights he isnt at home. It makes it harder. I thought that having sex everyday makes the sperm not so strong? I just bough 100 ovulation tests and 20 pregnancy tests.
My advice to u n the hubby is to try everyday until it happens
