Hpt Negative

I have done a lot of hpt's since i got the feeling i was pregnant but all came up negative except one which has really faint lines. I got intense pain both side of my ovary (more intense on the right side) the day i expected my period (no spotting)  which lasted longer than normal pms. There i thought it was the implantation, since then i started to test hpt but all of a suddend they were all negative except the one above mentioned. This is just driving me crazy and afraid what is going on. Sorry i just have to shout it loud here since i could not keep the dissapointments i feel just now. I was angry and open each of the used htp's before threwing them in the trash! 😁😭😢😖😡 anyway i am now 7days late of my period. Feeling twinges and cramps down there everyday. Bloated at night and headaches on and off. Breast are bigger than normal but no sore.
