No symptoms?

Had a miscarriage in December and got my period back 4 weeks later. We started TTC right away and as of today I am two days late but this time I do not have any symptoms as I usually do before I get my period like sore breasts a week before! This is very odd for me as it has always been the case. Do you think I could be pregnant ? Or has the miscarriage messed up my hormones ?
