For some, going off birth control can correct a period and make it come when it should. For others, you may only have a couple of good months, then your period starts to get abnormal. Have you gained or lost any weight during those months? I would say, check for pregnancy 1 week. Most tets say if you have a negative, to wait atleast a week to retest. If no period, check in with your doctor to make sure it's nothing serious.
Most likely you stopping the bc has thrown off your schedule. It can take a few months for that to happen some time. If you dont start in a week I would take a HPT.
Hiya, in my opinion i would say if your cycle is irregular then chances are AF is just late nothing more. The pill can mess around with your system, it takes a while for your body to re-adjust to what it considers normal, i speak from personal experience :-) Are the pains your experiencing the same as what you would get if you were on your period? As implantation cramping is usually a milder form to what you would normally experience, however each woman is different. If you have had unprotected sex then there is a possibility you could be pregnant, regardless if he pulled out or not, pre-ejaculation can contain sperm. And what do you mean by dangerous days? Days that you could be fertile? If you have irregular periods how do you map your dangerous days? And if your actually trying for a baby then there is no reason to freak out, if you are pregnant then its the most wonderful thing in the world, however if your not trying to get pregnant and are freaking out by the possibility of being so then why have un protected sex? Besides the pill there are other methods of contraception...
I would suggest re-testing in a couple of days, or if the pain gets any worse go and see your G.P asap
Best of luck
