Almost fainted!

After my spouse and I had intercourse earlier, I went to hop in the shower and had to think quickly to get the heck out and back to the bedroom because I felt so incredibly light headed. The only other time I’ve felt like that is when I got my wisdom teeth out as a teenager and took the pain meds without eating first.

Normal? I am 11 weeks 2 days. I would normally check my blood pressure, but we got a boxer pup over the summer and she ate the machine at her first opportunity with it.
