Possibly pregnant?

Me & my husband have been trying to get pregnant since I had a miscarriage in May, we were trying before that for 9 months. We found out the miscarriage was caused by me having endometriosis and PCOS. I stopped BC on November 30th and for the past few days I have had headaches and been car sick even if it’s a short ride somewhere. I’m only like 7 dpo so I know it wouldn’t show up on a test for a while.. it’s just frustrating & I can’t talk to anyone else about it.
