Jealous over ladies getting pregnant

Pip • Pregnant with a little boy • c-section is booked for 4th July 2016 at 8am ✨
All my friends have had babies and are on to trying for baby number 2. Recently a lot of them are falling pregnant or even people I know or have heard of. I get so jealous and actually cry when I find out.. Seeing woman on her gettint positives, makes me burst into years. I feel hopeless, due to the contraceptive implant I had for 3 years and only having it out 3 months my cycles all over the place and I just feel like it'll never happen. This will be my first, so I don't have a clue when I ovulate or how to know.. 😞
