Hello, my girlfriend is not having her period and she is late by 2 days we did UPT and it was negative. Her cycle is of 30 days and it is regular. On 24 January we had protected (condom) sex even I ejaculated in condom after pulling out and on 12 February we did this test and got a negative result. She is experiencing cramps from last 4-5 days sometimes mild and sometimes moderate. From last 3 days she had white discharge. We don't know what's happening. Please help.
