I had sex December 17 2016 around 10 in the morning. I saw the condom tore a bit so that night around 7 pm I took Walgreens alternative to Plan B, as the pharmacy said it was the same ingredients. I was due to start my period on the 28th of December. I had tender breast but not extra sensitive nipples. I always get sensitive breast on the side a week before I start. I started on the 24th of December instead of the expected 28th of December. I actually didn't start a full period it has just been spotting. Not even any smears on a pantiliner just residue and a smudge if I go urinate and wipe. After I started the spotting my breast are not tender anymore just normal. Today is the December 27 2016 and I felt queezy and like gagging in the morning. I ended up having to go potty and even though I didn't have soft or watery stool in cases of I was experiencing dairreah stomach pain and pressure. I have had to make bowels 4 times today but they were solid. Plus I feel bloated all at the same time this whole week and the spotting is lightening up Could I be pregnant? Did the morning after pill mess me all up?
