Faint positive - 2 negatives - feel pregnant

[IckleShield]

Hi, I’m just looking for a bit of clarification because I’m all a muddle!

Before period was due mid October I felt overly PMS. So I queried pregnancy but waited, then got spotting one day, continual dull cramping for the next day and light to medium bleeding, this is unusual for me as I don’t cramp much, let alone all day. Then spotting again the day after. So I thought, ok not pregnant. Then a week later I started to get lower abdominal discomfort. Twinges and dull cramping aches. I remembered these feelings from my first baby, (now 4) so I thought oh gosh I must be! Did a pregnancy test 3 days ago and it was a faint positive. Since then I’ve felt heavy in my lower abdomen, like period was about to start and dull cramping, but did 2 more tests today and both negative. I’m really confused. My boobs don’t hurt but I feel nauseous, I’ve gone off coffee and my head keeps feeling on fire. Even now my abdomen feels sort of heavy and a bit uncomfy . Does anyone have any feeling about whether they think I am pregnant or not? Chemical pregnancy? How likely is a false negative? Used clear blue x 2 normal and 1x digital weeks. Digital negative. Any help appreciated, thanks!

Test again with a different brand of test, a pink dye test. I once tested positive with a pink dye test, then tested a day later with a clear blue digital and it said not pregnant. It took a couple more days before the digital picked up the hormone. I just don't think they're sensitive enough in very early pregnancy.
Fingers crossed you get the result you want xx
