Hello, I had unprotected sex on 25th May which is last month and my date was supposed to come next week. Yesterday evening I had cramps and heavy moodswings which I usually get during periods and I ended up getting blood. I realized my flow is irregular. It is dark red or little brownish in color. Am I supposed to think I'm pregnant? I don't have any other symptoms related to pregnancy but the discharge looks unusual. This doesn't look like normal periods. What do I do? I'm at a remote location right now where I will not get pregnancy kits. Suggest please.
