When I was pregnant with DD2 I had a few contractions at 33 weeks. I was 10 hours away from my doc visiting family & just thought if I ignore it, it'll go away. I thought I'd go in there for no reason too & they wouldn't like me for wasting their time.
Anyway I went to the loo & there was a bit of brown blood. I freaked & told DH. He told his mum & she said to go lay down with my feet up. We decided to go home the next day & that if we needed there were plenty of hospitals along the way.
When I saw my Doc he said it was more than likely contractions & sounded like a bit of old blood. So nothing to worry about. But if it happens again to get checked & any more contractions to ring him. & I had to take it easy.
If you feel at all worried go & get checked. That is why they are there. Stress is worse for you than feeling neurotic. They will understand.
