Not sure if should be here...day of ovulation, nauseated...

Jessica
Today is my peak, have been BD for the last few days (mostly every other day) and about 30 min after breakfast (same cereal and milk i have had for several days) this morning I got severe acid reflux and after some tums, I feel really nauseated...I am really tired even after 8 hours sleep...emetrol not helping with nausea...could I already be pregnant?
