It took me like 5 months to get a regular damn period because after I loss the baby I was having two cycles in one month. This time I used the Glow app and ovulation test it helped me alot and it was vey accurate with my predicted start date of my cycle and ovulation.
About 7 months I got pregnant in August and now Im 6 months pregnant. But my miscarriage made my cycles very irregular so I think thats what took me so long.
