TTC & heavy periods after myomectomy

Hello,

Happy New Year to all the wonderful members here. I had an uterine fibroid(10 cm, right uterus) which was removed in Feb 2017, along with 2 Cm endometriotic lesion on left uterusacral area. We were told to wait for 6 months before trying. My periods have been sometimes light and heavy after the surgery. Last period was very heavy with clots. We are TTC for 4 months now. Is anyone else here TTC or got pregnant here after myomectomy? Also I have heard periods get lighter after surgery. The last one for me was the heaviest so far. Has anyone else experienced this?
