Im 4 days late now and 16dpo if my calculations are right.
I took a cheap test and it had a faint positive but I took a frer the next day and it was negative.
TMI but I had thick, clear jelly like discharge for a few days, sort of looked like fertile mucus but this was last week so it's unlikely to be ovulation unless I ovulated extremely late.
Now I have milky discharge, terrible bloating and cramps, really tender boobs and some lower to middle back ache. 
Could I be pregnant? Anyone have a similar experience?
