Possible Pregnancy Opinions

Di

So me and my partner have started to try to have another baby. This is the first try, so we had been going at it especially during my ovulating days. I have been feeling a tad more tired, urinating more frequently, and my nipples/boobs have been hurting lately but not previously(I do breast feed my 15 month old, keep that in mind). I took one those pregnancy tests that tells you a few days before your missed period and it came out negative, however I’m 2 days late. Did I take the pregnancy test too soon? Or would you think it is negative? As an fyi lately my period has not been on time. Also I did get pregnant on the first try with my first baby and found out 17 days later about my pregnancy, so I’m not sure if that’s considered pretty fertile. Opinions? Thoughts?
