My period last came on 21st March 2016. My cycle is roughly of 30 days. I had protected sex around 7th April. My period is roughly 14 days late. I have done two home pregnancy tests (around 27th april), and both were negative. I do have slight abdominal cramps. Have been having frequent headaches and slight nausea. No other symptoms seen.
Could I be
pregnant? Or what else could be the problem?
