Confused!!! Please help

Naila
So I have missed my period by 4 days no bleeding just off and on mild cramps. 1 day the cramps were a little more heavier I was sure it was my cycle and nothing. Took 2 test Friday and both was negative so I'm a little afraid to take more. However my boobs are sore and I pee a lot. No other symptoms , but has anyone else had an issue such as mine and then it was positive?
