Help !! 😳😞

I've had irregular cycles since coming of the pill but my last cycle was the 23/02/16 lasted 27 days bleed for 5 I'm now four days late for my next period due to glow .. On cycle day 18 suspected fertile week I had spotting lasted 3 days on day 28 I got a possitive pregnancy test I have done so many more and have come back barely visible or nothing on pregnancy test .. Which now brings me to now 4 days late cervical mucus i feel wet and cervical position is high closed and soft could I still be pregnant ?? Or what is going on any help much appreciated Thankyou
