in addition to what the other contributor said it's possible that you are pregnant and the hormone is not yet strong enough to show up on the test. i went through the same thing when i was pregnant with my second child. the hcg hormone wasn't strong enough to show up until i was already 4 or 5 weeks late. another thing to consider is is you have always been irregular then pcos is a possibility too. if i were you i'd consult with an ob/gyn soon. at least that way you can get some real answers and maybe some stress relief.
is there any way i can still be pregnant? . i was supposed to get my period on the 20th but i missed it so i took a pregnancy later that night. it came out negative and the following day i took one during the afternoon and it also came out negative. yesterday morning i also took when and it was negative too. ever since i've been having sex my period has been irregular and now i'm nervous if there is any way for me to be pregnant still after 3 negative pregnancy tests or could there be another reason why im missing my period?
