Will my period regulate?

Jenn • 💕 pregnant with baby #2 🤰

I have hypothyroidism and am on medicine to regulate it. Well, it has been in normal range for a few months but I started exercising and eating healthy, thus losing weight to aid in my journey to get pregnant.

My question is, I haven’t had a period before now in about 7 or 8 months. Is it normal for this first period to be longer than a normal one? I’m going on day 8 of bleeding.

Thanks everyone!
