Am I pregnant or just a period

Hi girls,

So in November I started taking birth control (but I was not taking them regularly at the same time at all and missed a day or 2) and i was having unprotected sex and he came in me a lot then in December I literally had a period for the whole month.. I would bleed like a period for a week not heavy tho at all (that's not normal for me) but then it was just dark brownish color the rest of the month very light and then some days it would be bright red and spot a little more then go away in an hour and just have brownish dark discharge and then in January I haven't had no period at all!!! And we've had more unprotected sex and he comes in me mostly everytime but I just haven't been feeling so good and discharging ALOT and I'm having little symptoms

Like

Really bad dreams

Cold flashes then hot

Cravings

Sooo moody and emotional like crazy

Lots of discharge

Gaining weight lately

Headaches

Really sore back pain

Cramping very little tho

But what do you guys think should I take a test to see or will I probably just get my period hopefully soon?
