Okay so I had sex on the 22nd of January, and my partner finished inside me. Right after we finished, I started bleeding so much and started having painful, painful cramps and a massive headache. I did not take a plan B at that moment because the pain was so excruciating I did not want to think about anything except wanting to take an ibuprofen, is there a chance I could be pregnant ? I’m supposed to start my period in 2 days, though I haven’t had any symptoms whatsoever and no cramping at all. Has this happened to anyone ? Any suggestions please ?
