I did! I FREAKED and I got checked THREE TIMES by three different doctors and all they found was a UTI that had no symptoms. I knew that's not where the blood was coming from lol I never found out what it was, but I also had a polyp on my cervix that they'd found at my first exam. I'm thinking it may have popped and that was also what caused my bleeding at 10 weeks since they found nothing then, either. I hate not having answers but when they're not finding anything even in ultrasounds that's what we're left with lol. Another possibility is that if they did an exam or if you had sex recently, that can cause a little irritation to your sensitive cervix and can cause spotting.
Yea tiny spotting is normal what my mom told me is that when the baby is growing sometimes puts pressure as long as ur not in pain and the nurses said that as long as ur not bleeding pads through pads it's ok also lol I experienced one spotting 29weeks I had sex like 5 times the day before thay was a cause of it I panicked went in and everything was ok
