Specs/spotting

Marissa • 🌈 8/20 💗9/21

Hello ladies!! 18 weeks today, and last night had verrry light pinkish-red spotting when I wiped. I went to pee throughout night and that was the only episode. No abnormal pain, no cramps, and sex was about 24hrs before. I’ve reached out to my OB but trying not to freak meanwhile. Anyone experience similar?
