I've been on the pill for over 10 years and always had my period on time, never more than a day late.
Last month I missed a few pills due to moving house and generally being really busy but I wasn't worried as we plan to start trying for a DC around Autumn time and so if I was pregnant I would be pleased and there would be no question whether to keep it, it just wouldn't be the perfect time (but is there ever?!).
A few days before my period was due I had some very light pink blood after I wiped (TMI) I googled what it was and found it was implantation bleeding. This was my first indication that I might be pregnant. My period was due last Wednesday, and Wednesday came and gone and no sign. I took a test and it came back negative. I continued to expect my period and still nothing, I have taken a further 3 tests and all are coming back negative. I'm now due to start taking my pill again and I'm not sure if I should if there is a chance I might be pregnant. I have some lower back pain and I have felt some twinges but no other pregnancy symptoms.
Last night I woke up and violently vomited up my dinner and my stomach has felt fragile all day but that isn't how I would imagine morning sickness would be. Basically I'm scared. I've got a doctors appointment tomorrow but I was just wondering if anyone had been pregnant but it hadn't shown up on tests?
