Okay...I had a baby 13 months ago and I knew from almost the date of conception without a doubt that I was pregnant. I am feeling the same way now but without as much certainty. I have been on the pill for a few months now...though I missed and entire pill last month and haven’t been taking this month's pills at the same time everyday. According to the pill pack i should have started my period three days ago and I am normally as regular as the moon cycle. The past few days I have been extremely irritable which isn't normal for me even before or during my cycle. Also a couple days ago I felt some light cramping in my lower abs...not like menstrual cramps but similar. I have notice a very light pinkish tint when I use the restroom today and about five days ago also but nothing in between. Now even that has stopped. I took a pregnancy test yesterday morning when I first woke up as I know that is the best time. It was negative. With my first child my period was still two days away and I tested positive. I have been under a bit of stress lately with work and everything also. Could it just be stress or is there a good chance I really am pregnant and if so when should I test again?
