Me and my boyfriend have been trying to start a family and we have been trying every day this month, he has went in me majority of the month so I'm sure I didn't miss my fertile days .. I've took 2 pregnancy tests and both came back negative (could it be too early to read?) currently 6 days late and just started bleeding (note when my period is near my boobs will be sore and lower back pains etc.) this month that did not happen and I have light bleeding that was heavy for about a couple hours and dark colored, and now a couple hours later really light and light in color (no chunks, globs)  no pains but a little cramp every now and then in lower abdomen. Could this be spotting ??? Could I hopefully be pregnant?? Please let me know in detail all possibilities of what this could be.. 

thanks!!!
