I was about 5 days late for my period. My menstrual cycle used to be very irregular, but was getting more regular. However since it's been irregular in the past, I wasn't too concerned.

I took a home pregnancy test, it was negative. I was still stressed and then I began feeling crampy. Instead of getting my period, I got light brown spotting.

My period before this was unusually heavy and came rapidly during a time of emotional stress. This period also came rapidly during a time of emotional stress but, as I said, is light and brown.

I have been both nauseous and unusually hungry, alternating. I get headaches and sometimes backaches. I have trouble sleeping. Breasts are kind of tender. Little more tired than usual but that could be from stress / new medication. Feeling a bit bigger than normal but no weight gain. But I almost feel like I'm just trying to prove that I'm pregnant and all these things could be caused by something else. But maybe not.

I've had unprotected sex but used the "pull out" method (which I shouldn't do, I know, I know).

I was recently diagnosed with depression and am on anti-depressants. I googled whether these would affect my period and it didn't seem to.

Between my two periods, I only had sex twice, both times unprotected, and neither time did my partner come even close to ejaculating before pulling out.

Before that I had unprotected sex multiple times with the pulling out. Not on any birth control.

I'm just confused. Is there a chance I'm pregnant? With the period before, etc?
