Hi, everyone reacts differently to the gel, sometimes it works, sometimes it doesn't, but i had the gel for my 2nd and this is what happened to me.
The day before my due date was told to come in to be induced. i was given the gel at around 11:30am and was sent to antinatal to wait. at about 4:30pm, started having contractions, quite strong ones too. a nurse heard me and came to check on me and said no they are not contractions, the gel can cause this to happen so you're fine. She said i was due to go back to maternity ward for another lot of gel at 6pm so i had to wait for that. i was getting lots of strange looks from everyone as the contractions were pretty intense. at 5:30 the nurse decided to get me ready to go down a bit early, but i was in so much pain (good pain IYKWIM) i couldn't walk, so i got in a wheelchair and was sent down. as i was wheeled in, a midwife said to take me into the room where we just get monitored, not a delivery suite, and then another midwife said (after hearing me have a contraction) said no no, straight into a suite. contractions coming hard a fast, but inbetween contraction had no pain at all and was having a great conversation with DH, interupted by the contractions lol! they let my waters break on their own, which happened at about 7pm, and bub was born at 8pm. the only drug i had was a bit of gas which just took the edge off towards the end. the pain was intense but it was a weird sort of quite bearable pain, i actually enjoyed the pain if that makes sense, but it did happen very quickly. my first labour was 28 hours, epi, forcepts, bub was posteria, very bad (but not induced) and my labour with DS2 was great and i had the gel.
but like i said, everyone reacts differently to the gel, i didn't find it traumatising at all, in fact quite the opposite, so good luck and i really hope you are one of the lucky ones like i was.
