Hi i am so confused I'm not on any kind of birth controll and have been ttc for 6 months after having iud removed I was due to get my period on the 10th and it's never late it still hasn't came I've had pains like its about to start tho and now the pain had gone just feel a funny feeling in my stomach I have done 3 hpt and all negative. Also exactly a week before my period was due I had period like cramps for an hour or 2. I just need some information I'm worried incase it could be something else causing this to happen
