Really bad pain when I wake up

Jennifer

The past couple days I've noticed I'm being woken up really early in the morning due to severe pain. I'm assuming its trapped gas, I'm just under 20 weeks and as far as I'm aware not eating or doing anything that would contribute to such bad gas (aside from being pregnant obviously). I only had this at 30+ weeks while on iron tablets with my son so I'm a little concerned and just looking for reassurance really. I'm not constipated or anything, but the pain is so bad I can't stand up straight and I feel physically sick. It takes about 10-15 minutes to pass (tmi but usually with a couple small toots 🙈). I'm just getting super exhausted with how early it's waking me up. I also have a toddler to look after, PGP/SPD, and I keep getting incredibly out of breath/light headed. Is it definitely just gas? I get the same pain when wearing anything a little tight over my bump.
