Missed my period for 2 months

Hi, so I missed my period for March and April and as having an active sex life, I thought I was pregnant. But I already took pregnancy tests twice (on different days) and both ended up negative. Is there something wrong with me or is it too early for pregnancy tests? I am planning to take a blood test since some of my workmates say its more accurate(?) in telling if you’re pregnant. Thanks to anyone spending time on this 💗
