Hi, Im a 28 year old female, I have 2 children & I was sterilized 3 years ago this March coming. My periods have been the norm 4 wk cycle since the op, until now. My last period was 11wks ago, I did a hpt 4wks ago & another last week, both negative. Im emotional, moody, lethagic, no patience, heartburn, back ache & an on/off dull bruise like pain on the right hand side lower abdomin. Also about 8-9wks ago I went for a wee & when I wiped myself there was a thin streak of watery blood, as I was at work I put a pad on, next time I went to the toilet there was no blood & none since. Could I possibly be pregnant?
