labour?

I'm 41 weeks exact today. Had my first stretch and sweep Wednesday just gone. Had my second one today. Wednesday I had some cramping on and off but after a few hours it went away. I also had some bleeding (due to the stretch and sweep.) today about 4 hours after my stretch and sweep i had cramping again. It started off mild but as the hours have gone by it's become very strong. The pain is bearable but it's a hell of a lot stronger than what I was getting earlier on and also on Wednesday. I've started timing the pains, they're not consistent. One minute the pains are 5 mins apart then 7 mins apart and I've just had one come in at 2 mins apart. I've noticed tightening with these pains as well. Since last night I've been having loads of yellow gooey discharge every time I go to the toilet. I've run myself a bath to see if that helps me at all. Im a first time mum so I don't have a clue what I'm looking out for when it comes to contractions. By what I've described does it sound like contractions? Thanks.
