I am 10 days late me and partner are trying to get pregnant we had sex at my most fertile point and before and after that I have cramps as if I'm having a period which I don't get when I have a period become very tired lately and feeling sick in a morning? X

First, not to sound negative, unless you were tracking basal temp, you have no idea where you "fertile time" was, ovulation can not be tracked properly by online computer "games" or phone apps, many women do not follow that daily schedule.

With that said, it takes 3 days for sperm to reach the egg and normally there are no signs at all, until you are late,

So 10 days is late, it is a little early to test, but you could try using first urine of the morning. If negative try again in 5 days.
