I’m two days post my second Pfizer vaccine and currently 20w4d pregnant. No side effects other than a sore arm (feels like a mild bruise/ache, it’s barely there today). I had my first vaccine 7 weeks ago and had no side effects then either bar a sore arm, which was worse this time but not bad at all (same arm). I’ve since had my anomaly scan and check ups with my obstetrician and both baby and I are healthy and well, growing happily as expected.
