I have posted before here
and I have another question

I am on the 21 days cycle

I started my period on sunday 7th march and finished on the 10th and I had unprotected sex on the 11th and the afternoon on the 12th and I had all these symptoms and I am only eight days away from my period due date and I am normally in some tummy pains a week before and then it goes away then I start my period.

Some symptoms that I have
Cramping
Heartburn
Abdominal Pains (Near underwear line)
Tiredness
and
Low back pains

Shall I take a pregnancy test now or wait till I have missed my period????

I know there is a good chance that I could be pregnant

thanks
