Don't stress!!!!!! The most important thing to remember is that if you are scared during labour that will stall it just as much......you can TOTALLY do this!!!!
My baby was back to back and sunny side up....I only had laughing gas and had a tear 'up front' due to his weird positioning but honestly it was so exciting to hold that baby that I didn't even care.
I knew my baby was back to back and when I woke up four days after my due date I had a period cramp and as soon as I stood up it turned in to a back cramp. I had back labour, not one cramp up the front. It felt like my back would tighten up here and there and I had a midwife appointment that morning and she checked me for a sweep, said I was 1-2 but didn't want to do the sweep because my baby hadn't descended. Her 'check' started my labour and when I got home I had my bloody show.
I sat on the couch and watched netflix all day and tried to nap as much as possible. The back cramps were totally manageable all day, by the afternoon I had to breathe through them but I wanted to labour as long at home as I could so I just kept at it. At around 11pm I was starting to really feel it and called the midwife, when she heard I couldn't talk through the contraction she came and checked me and I was gutted to only be 3-4.
She told me to keep going and she'd meet us at the hospital when I was ready. The contractions ramped up again and by 4:30 I was yelling at hubby to phone midwife, tell her I wanted an epi and that I was heading to the hospital. I was six centimeters when I got there!
The BEST thing for my back labour was being in all fours in a huge tub and when a contraction would come my OH would use a showers head with super hot water and spray it on my back during the contractions. After awhile I needed the laughing gas and just kept plugging away in the tub. Was able to laugh with midwife and OH between contractions. By 9:30am I was fully dilated but my water hadn't broke. Midwife broke it and that sent me in to instant transition which was difficult but by that point the longest part was done and there was no going back.
I won't lie, it felt like my butt was going to explode when I pushed but my midwife held a hot washcloth on my perineum to offer support and I was scared to push because it hurt so it took two hours of pushing. Baby's heart rate stayed great the whole time. When he was crowning I was screaming out "I'm tearing!!!" But it was just the ring of fire. I actually tore on the final push out and it was his beautiful little face that did it since he was in there wonky. At 12:08pm Wesley James came in to the world and it was the best moment of my entire life.
Sorry that was so long, but I was a scared FTM like you but I made a plan and stuck to it, I wanted to labour at home as long as I could to avoid intervention, have a natural birth and use the tub. Talk to your labour 'team' to get the support you need. My baby was 8lbs5ozs.
PM me any time with questions and don't listen to the horror stories!
