I have been spotting for the past 4 days my cycle is suppose to be on the 3rd of October. The spotting is only when I clean myself. I'm suppose to start taking clomid but how do I know if this was my regular menstrual cycle since it is always 4-5 days but very heavy. I have a lot of the pregnancy symptoms but that is also because I have the flu. However, I do have lower back pains like if its going to start. My last cycle was on the 5th of September. Any idea what this could be. I took 2 hpt on the first day of spotting and they came back negative. Should I take another one?
