I HAVE A POSITIVE PREGNANCY TEST WITH CRAMPS AND BROWN DISCHARGE AM I GETTING MY PERIOD

I have the same symptoms. About 3 weeks ago, i noticed that my breast were sore. A week later, I `had nausea, mild stomach cramps, back pain, couldnt sleep good at night, couldnt sleep on my stomach without pain, headaches, and very vivid dreams. This week, the symptoms only got worse. I cant eat most foods with out feeling nauseous, i feel emotional over little things and this morning, I notice light brown stringy (gel like) discharge and if i keep wiping it fades and is very very light brown. I normally have my period every 28 days and the first day is usually heavy. Last Month, after having unprotacted sex with my boyfriend, it came on a Monday (two days before it was suppose to). And now its Monday (4 weeks from my last period) and i just have those symptoms and light brown discharge. But the thing is, for the last 7 months i've been on birth control (Ortho Tricyclen Lo). I would sometimes miss a pill and take it later or forget to take it the same time everyday (and take it 1 to 4 hrs later). So i am pretty positive i am pregnant although i do not know for sure. I stopped taking the birth control just incase i am and started taking prenatal pills.... If u have been having unprotected sex and not used any birth control, than more than like you are pregnant especially if you took a preg test that said POSITIVE. Take some prenatal pills and make a docs app. Hoped my super long story helped lol.
