Pregnant???

xox

I was pregnant last year n gave birth on the 10 November n I’ve had one period since then,I was meant to get my period 2 weeks ago but I haven’t.. me n my husband have been having unprotected sex since 2 weeks after labour..sometimes pulls out n sometimes doesn’t however I took a test 2 days ago n it was negative so is it too early or are my periods all mixed up n all over the place???
