Hello.
It has been 6.5 weeks since I had sex and I've had 7 negative pregnancy tests, including 1 negative blood test at 3 weeks. I had sex 2 days before my period and the pull out method was used. My next period was on time, lasted for 7 days, but was fairly light with bright red bleeding from day 2 to day 3, and browner bleeding on the other days. I have had lower back ache from week 3 until now and frequent bowel movements. These have not been painful. I've been slightly nauseous but have not thrown up, just a bit gassy. Could I be pregnant? And could it be ectopic?
