possibly pregnant, but most likely not..

My husband and I had sex at 1 DPO, according to glow. I had my nexplanon implant taken out May 10th, we had sex the 17th. I've been having cramps, one day was slightly nauseous in the am, and I feel like my boobs have gotten slightly bigger. But I having a feeling it's all in my head since I want to be pregnant. My husband has it in his head that it's going to take 6 months to a year for my body to "regulate" itself and be hormone free. I asked him to pick me up a test or 2 from the store and he said ew and gave me a dirty look. I know he wants more children, we already have a daughter.. is there a chance I could be pregnant? Don't tell me to buy a test, I already am going to. Why would he be saying ew if he wants more kids??
