Was taking birth control & used a condom the last time I had sex on Feb. 20th. I quit taking the pills in March. I got periods every month regularly except at the end of May..I am now 4 days late..I have taken 3 hpts all negative but u have gained sum weight & ppl are constantly asking am I pregnant..I even think I feel baby movements...& I by mistake lost one if my b.c. pills about 2 weeks before I had sex..could that have caused a problem? & if so I'm technically almost 4 months why am I still getting a negative result??
