Starting to stress 😓

Basically had sex last night.

Had pink spotting which was normal and stopped fairly quickly.

Started having on and off back pain which after 5 hours sleep i cant really notice anymore.

What im worried about it that my whole belly has gone hard. I am 39w4ds and this has never happened before. I thought after 5 hours sleep it would have gone back to normal but it hasn't.

Bub was quiet yesterday before hand and ive only been getting tiny movements this morning but i have only been wake for half hour and havent eaten anything yet. But I'm really starting to stress about my Baby 😖
