I had unprotected sex on the June 29th (today is July 21st). We used the pull-out method and he did not finish inside or outside of me. However, the next morning to make sure, I took the morning after pill (plan b) within 24 hours to make sure. Before I continue, I did not have my period for June. I usually have my period on the last week of each month. Continuing on, 6 days after I took the morning after pill (around July 5th), I started to have cramps. Afterwards, I had a light, brown spotting, and the cramps continued on for couple of hours until I finally started what I considered to be my period for june that came late. This period continued until the July 8th or 9th (so for 4~5 days). The cramps were there, the blood was bright red (normal period colour), and I had to change my pad 3~5 times a day for the first couple of days. And 1 1/2 week passed and I began to have what I considered to be another round of period symptoms. Bloating, constipation, acne, fuller breasts. This, of course, freaked me out and I took a couple of pregnancy tests (sensitivity: 25miu) which all turned out to be negative. However, since a couple of days ago, I ve been urinating a lot more frequent than usual and feeling discomfort in my lower abdomen. And as well, the symptoms I ve been noticing are a little different from my usual period symptoms (im irregular when it comes to my cycles by the way). So today morning (July 21st-3 weeks since intercourse), I took another home pregnancy test which turned out to be negative again. Am I pregnant?
