Irregular periods - how far along am I?

Rae

I’ve downloaded so many apps and used just about every <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">due date calculator</a> that comes up on google but they are all giving me different answers and I’m not exactly sure which one is right or how to even figure the math out myself.

Some of them are saying I’m 8w0d today, others are saying I’m 7w0d and some are saying I’m 6w5d today.

A few of my previous periods are:

December 7, 2018 - 4 days long

January 11, 2019 - 6 days long

February 27, 2019 - 3 days long

April 8, 2019 missed period (projected by a <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period app</a>)

April 10 - positive pregnancy test

Some apps are saying my cycle length is 35 days and others are saying 40 days so I have no idea. I know nothing is accurate until you get an ultrasound but I haven’t been to mine yet.

If anyone has any ideas or input it’d be much appreciated! 💗
