Abigail Noelle • 24. Married. Angel Baby 👼🏽 . Trying again 👶🏽.
Okay ladies so it's been a long journey for me . Me & my husband have been trying for 2 1/2 yrs to get pregnant finally found out back in 7/3/16 I was pregnant .. 6w4d found out I misscarried . Didn't get my first period as they called it till ( mid September ) but it was more spotting light pink and for 5 days . I've always been a average to heavy bleed and for weeks at times . Another doctor diagnosed me with a mild PCOS condition . And from then on I didn't have nothing till 2nd week of December . I've had checkups with my new obgyn same as my doctor who I was seeing for my pregnancy . She's done blood work and sonos and everything's fine she says my body's just taking longer to recover from my miscarriage . She did start me on metformin 2x a day to help with ovulating she says . It's been almost a month and the 2-3 day on it I start my period back in December . Since I've always been irregular idk how long my cycles are and I just go with the flow of glows calendar so it says this weak I'm ovulating and today's my peak days . After months of not getting pregnant after thanksgiving I decided to give it to God and not stress or track it . But I do see my calendar and notice its ovulating weak . But my concern is I do remember spotting my lasting pregnancy in ovulating weak . Yesterday I started with a dark discharge & moved to light pinkish bleeding . Back to dark discharge today and now darker blood . Would y'all consider this a ovulation thing or just it's my period since I am on this new medicine and I haven't a many period since the misscariage and it's my body trying to go back to normal . Please help any recommendations any advice would me much appreciated .
