Has anyone experienced this during early pregnancy?..?

My fiance and I have been TTC for about a year now. My last period was Nov. 23 and my period has always been about a week off, for example, my period comes about a week late. I expected I was ovulating on Dec. 20th because of EWCM. We BD'd on the 20-25. We also read about people successfully concieving when using real eggwhites as lubricant to increase the chances of getting pregnant. Apparently it mimics the affects of EWCM and makes a better enviornment. After BD I sat with my hips up for about 20 min. On January 7th I had light spotting, only when I went to the bathroom. It was light pink and very watery. The next day it got a little heavier and then ended up becoming like a normal period. This bleeding only lasted about two days, and overnight I had a tampon in and the next morning, there was nothing on it at all. Later that day, it started back up. The bleeding continued to be this way, ( come and go throughout the day ) for around two more days and then stopped completely. Usually I have a fairly heavy period, to where I need to change a tampon every 2.5 to 3 hours. The bleeding stopped a few days ago, however, I still have the same symptoms that made me expect pregnancy in the first place. I still have sore , more frequent urination, and have had mild cramping and gas all day. I have had headaches the past few days, and I dont usually get them. I have been overly emotional and moody, and exhausted no matter how much sleep I get. I have had random hits of nausea throughout the day over the last few weeks. I know that we have been TTC for a while, so my hopes could be high! But I was just wondering if anyone experienced any bleeding like this in early pregnancy? Also, any tips for helping conception would be greatly appreciated! Thank You for reading my post! God Bless!
