Hi everyone, I am 25, married and I do not have any children. I need some help to know when I should be able to take an effective pregnancy test. My problem is that I am on the progesterone only pill so therefore I do not get regular periods. I have forgotten to take my pill of a few occasions (bad I know), but I was so used to having the implant in and not having to worry about taking a tablet every day. On boxing day (12 days ago), I had what I believed to be implantation bleeding (brown discharge / blood which lasted less than a day), and since 28th December (10 days ago) I have been feeling dizzy and extremely nauseous without being sick. Due to this, I have no appetite whatsoever and it is like I have to force myself to eat. I also have started to experience headaches, I have had a migraine (which I never had before in my life) and my love for coffee had suddenly left me. I did a pregnancy test a few days ago and it was negative (I have a feeling it might have been too early to test in any event). Please may someone advise me when I should be able to take a pregnancy test? Any advice would be greatly appreciated!
