35 weeks pregnant could labour be starting soon?

Since yesterday I have had the worst shooting stabbing pains in my vagina also quite a lot of pressure in my bum. Was aching all over had no energy constantly felt sick and had really bad heartburn,never had it before. Had constant period cramping all day and night.

Today woke up in the worst pain I'm feeling really crampy still along with constant tightenings and shooting pains in vagina.

Went for a wee not long ago and my bits are very swollen literally bulging don't know what that could mean. Also past 2days since all this pain I've been getting yellow tinged discharge which is normaly clear/creamy coloured.

Any help would be fantastic sorry its so long lol xx
