I got married few days before. Me with my husband tried for first intercourse, with and without protection, but we couldn't make it. Due to improper angle I got a minor cut in vagina. After that night, we tried with fingers only. After 2 days from our first attempt I was feeling low. I had heaviness in head and stomach and pain in lower back and pelvic bone around groin area in right side. Next day onwards, I had little brown discharge and pain in lower back, groin and both legs. Please let me know is this the sign of pregnancy? Or anything else to take seriously.
