I'm a 30 year old woman. I use the mini pill, but missed 2 pills during ovulation (I track my cycle) and my spouse and I had unprotected sex both days. I'm now 6 days late, and 4 negative hpt. My spouse and I had sex today and after when I went to the washroom and wiped there was a light streak of blood. Did I ovulate late and that's implantation bleeding? I did experience cramping and lower back pain for 3 days, after the day of my missed period (Oct 13th). The first day of my last period was Sept 15th. Could my period be skipped due to missing those 2 pills? Or could I be pregnant? I got a blood test done and will get the results Monday. If the test is negative and my period doesn't come should I take another test and when?
