Confused Pls Help

Hello ppl, I had a miscarriage a few months back and since then my period flow was light..... This month I've missed my period for about 8 days and having this clear or sometimes milky white discharge (Tried testing on the 3th & 5th day but was negative..... And a dull stabbing pain yesterday at my right side of hip...... Had sex a few times like 3 or 4 days before ovulation.... No sex during ovulation, 1 day before or 1 day after....... Could I be pregnant?? #advicepls #hopingforababy
