Hi. Am 40 +2 and had a stretch and sweep today. Have been having cramps all afternoon every 9 (ish) mins since. But it's all in my back and tummy doesn't tense at all. Is this the start of Labour?! I've been having trouble with iron tablets too, giving me constipation (sorry tmi!) So thought it might be that but it's very regular. Had a nap earlier and it subsided a bit but has come back which is making me even more confused! Any ideas?!
