Could I be pregnant?

I had sex twice on my highest ovulation days. About a couple days later I began feeling cramps and nausea (it’s happens everyday now). Well yesterday ( 9 dpo) I was eating noodles and began to feel nauseous half way through the bowl and had to run to the restroom because I was gagging about to throw up but nothing came out. For the past two nights I cant sleep. The night before last I couldn’t go to sleep until 3 am and still woke up 6 times throughout night tossing and turning. Last night I went to sleep at 12 and couldn’t stay asleep either. I also have increased discharge that is creamy and white. Could I be pregnant or could it be something else. I got two negatives ( 7 and 9 dpo).
