Do i call midwife or just rest ?

So a bit of back story..im 14 weeks pregnant and i have bleeding again,nothing major just when i wipe. Only a tiny bit gets onto pad. I've had this exact same thing twice now,once when i was 8 weeks and again when i was 13+3. I had scans both times and baby was absolutely fine. And nothing can be seen to causing it. It stopped after rest and only lasted a day. I also had an anti d injection as my blood groups o negative. Ive been told to see my gp for a pelvis check as it may be coming from there. I have a phone consultation with my gp today before my actual appointment, so I'm going to mention todays bleed to her. I really think this time is because i spent nearly all day yesterday out and about and didnt properly rest untill late evening. Do i ring the hospital again ? As they know theres nothing wrong with baby. Or just rest to let it stop like it always does.
