Hello, I ama 22 year old female. I had unprotected sex with my husband about 2 weeks ago. About 5 days after sex, I had some light bleeding that lasts 2 days then stopped. I've taken many HPTs and they have been negative. I haven't yet gotten my period for this month yet either. Is there a possibility I could be pregnant and if so would a HPT be positive when I miss next month's period?
