My period is late, but this is nothing unusual as I'm very irregular. This past week (the second week where my period should have came but didn't) I've been experiencing: hot flashes, nausea, queasiness when eating, I've been feeling confused and have found simple tasks difficult, severe mood swings, last night I became very lightheaded out of nowhere for about a minute and my fiance has been marveling that my boobs have gotten bigger but I'm not so sure. I'm just tired of wasting money on pregnancy tests since my period is so irregular, I have pregnancy scares often, but I never had physical symptoms like this. Also somethings to consider: I've been under a lot of stress as I recently lost my job and I recently visited a friend in the hospital who had viral meningitis, although I entered the room with a facemask and i washed my hands before and after entering the room. My fiance and I have been using condoms only. Should I get a pregnancy test?
