I am on week 3 will take day 4 pill tonight of a 28 day pack. I have been getting these period like cramps off and on all day. Sometimes they can be somewhat intense for a few seconds then go away. Is this normal for this pill? This is my first month on this brand. We have had unprotected sex twice this month with him ejaculating in me only once. I have also been taking it at the same time each night with only 2 nights being an hour or so late.
