39 + 4 weeks pregnant and have had a few sharp pains up inside my vigina ?

I have been having tightenings since yesterday late after noon think they could be braxton hicks but have been quite in tense and painful like cramps , they was coming about 20 mins apart untill this evening when they started to get easier and wasn t coming as often but then I went for a Wee and had a show then the pains eased off but was just sitting down and felt like baby pushed down hard and I had a really sharp pain up in my vigina and it felt really strange too ? Is labour near ? I have had a fake labour before so that is why I am confused and I know some times labour doesn t start straight away when you have a show , any ideas ? Thank you in advance
