Second pregnancies you get way less appointments, I am consultant led but didn’t even get offered a community midwife appt this time. From my 12 week appointment I didn’t see anyone until 28 weeks (except for my anomaly scan). Definitely speak to your GP re the aspirin- the letter from the hospital will state when you should take it to (I know this varies from trust to trust, some say until 40 weeks mine is until 37 weeks). Also mention the pain, I had this and it was PGP and was referred to physio (the birthing ball was the only place I could sit near the end, but it gave a lot of relief in that particular area!). It’s frustrating, but you know your own body so make sure you advocate for yourself when you don’t think something it right
