Hello. I had protected sex slightly over two months back. Still, to be sure i took a home pregnancy test after a week. it was negative. I missed my period after that. took another test, again negative. i have been irregular before too, and have skipped a month also before. so, i thought this is relatively normal for me. but now, i should have started menstruating two days back (after missing the previous month), but i haven't. I can not go to a doctor alone and i do not have anyone who i can share with this right now. What are the chances of my being pregnant? or is it something else that i need to worry about?
