In need of help!

Hello ladies I'm new here and my husband and I are ttc baby #5 (our last one).. I got my period on Feb 9th and I'm still on it, (I have one fibroid tumor on my endometrium thankfully it will not come in between with me getting preggos nor will it make the pregnancy high risk) it makes my period last more than the usual, is there a way that I can adjust my period here on the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> so I can have the correct dates for my fertile and ovulation days? If so can you please help on telling me how bc the app on it's own assumes I get it for only 4 days when I actually have a 35 to 36 cycle and I want to change that! Thanks.
