Miscarriage fear - any advice?

Hi guys, just wondered if anyone had any advice or reassurance for me.

I had a m/c last November at 7+2 weeks but was told the pregnancy had stopped at around 5 weeks.

At that time (5 weeks) I was having frequent blinding migraines with nausea and photosensitivity and shortly afterwards I noticed my sore breasts and bloating had improved.

I'm currently 6 weeks and had the worst migraine today, exactly the same. And my breast tenderness has completely gone. Has anyone else experienced symptoms going away like this and continued with healthy pregnancy? I've lost all my excitement over it now, and my first midwife appointment isn't for another 2 weeks (going on holiday tomorrow). Thanks xx
