When during pregnancy you get free prescription, as I remember I have to fill up form. On my booking appointment midwife said she will send aspirin prescription to my GP to take 12 weeks onwards and I can pick it up in couple of days. I'm over 9 weeks now, do I have to wait until 16 week midwife for free prescription or can sort it out earlier. To be fair I'm not willing to pay £10 for aspirin, would just buy over the counter until I get it free.
