IVF pregnancy- Cysts. 6w4d

I just had my second ultrasound-- everything looked good--we saw a flutter of the heartbeat and everything(first preg). The tech did see some rather large cysts on both my ovaries. She said its normal with a fresh <a href="https://glowing.com/glow-fertility-program">ivf</a> cycle -- and put me on pelvic rest for a week and a half until my next ultrasound. I'm suuuuuper bloated but otherwise feel fine. She said if I experience severe pain to come in. 
Anyone else experience this? It was a little freaky bc they cysts looked HUGE on the screen!!
