It’s probably nothing as sex can cause bleeding during pregnancy, but you could always go in to get it checked out. I ended up buying a baby Doppler to reassure myself as sometimes our daughter was quiet too. I would maybe ask your dr about the aspirin though. I was told to only take Tylenol during pregnancy
A lot of women bleed after having sex, especially if you have a low-lying placenta which might not have been discovered at 24 weeks. I’d say if you’re worried and the not knowing is going to cause you more stress then go to triage and get checked out but I wouldn’t wait to feel movement as baby’s don’t have a routine until 28 weeks and even then it’s not common for them to stick to a pattern xx
I had the same when I was pregnant around 25 weeks and there was blood after sex. I rang the antenatal clinic to get some advice and they said to come in because I couldn’t feel baby moving for a few hours. Turned out everything was fine and that the blood can happen sometimes. But if you’re ever worried or unsure, call the antenatal clinic for reassurance and for peace of mind. The midwife I spoke to when I went in told me to call as many times as I need to because it’s better to be safe than sorry. Hope this helps, drop me a message if you need to chat to someone 🤗 xx
