Am i pregnant?

Ta

Ok ladies I have a serious question. So hubby and I are ttc we bd around the time of ovulation and the day I got the positive on an LH test and even bd after the LH surge. Now my usual period symptoms consist of vomiting, migraines, mood swings, and slightly tender breast. This time around the cramps weren't as deadly as they usually are and my breast are 10x more sore than usual. The nausea carried out throughout the day when I usually only get it the first day of my period in the morning just before it begins. The nausea this cycle carries out throughout the day which is unusual and I have really bad bloating, and my cm is being produced way more than usual and is a milky white color. My period is always on time as soon as I wake up and its heavy flow blood clots and everything for six full days usually. (Sorry for the tmi.) Now this months "period" was four days late and on the fourth day of it being late I had very light bleeding not even enough to fill up a pantiliner and usually with a normal period I go through a whole box of tampons within a day or two of my regular period. The "blood" was pink at first then turned to red and then went to brown discharge and carried out to midday of the following day. Now the real question is could this be a possibility I am pregnant or a chance that im not and that this is just a light period. How long should I wait to take a test? Your advice would be very helpful ladies. Sorry for it being so long I'm just concerned.
