I keep asking& not getting much help

Okay. I need to figure out when i should test.

I had the implant removed March 11th 2018.

I had 2 periods that month. I had sex April 5th & 6th. I have not had a period at all , but i am experiencing symptoms; nausea, acne in places i wouldn’t usually get it, cramping really bad , super tired, itchy nipples , headaches & weird cravings & mood swings. These are not normal symptoms for my period. For my period its just cramping & wanting sweets. When should i test? Please help.
