take hpt, blood test will be more accurate to know.
Are you trying on your own or with fertility drugs?
I am only 4 DPO so I am guessing that it is too early to get a result on a hpt.
I am not on fertility drugs.
i wouldn't bother testing until 10 dpo, but many women don't get a BFP until 14+ dpo
and there are no symptoms that are indicative of pregnancy. some women have all kinds of symptoms and are not, some have none at all and are pregnant.
so try to relax until it's time to start testing
good luck
