Jasmine • 💙 👶🏽3-6-18.... TTC #2
I was prescribed medroxyprogesterone for 10 days by my doctor because I was on CD 62 with no signs of AF . It's now 3 days after taken the pills and I'm happy to say AF has arrived . My question is when do I start my ovulation tests .? Since I'm irregular I don't want to miss it . First time
Using them .
