Help I’m so confused!

Paige

A little long but please help! So I’m 10 months post partum. I started getting periods around 6months PP for reference and was getting a period about ever 38-40 days for my cycle lengths. I had a period start april 20th. And a period start May 27th and ended June 1st. Im talking like full blown bleeding and was definitely a period with how heavy it was because it was just normal to me. That day I started my period I had taken a test as I’ve been doing monthly just because and it was negative and then I wiped and bam period. So fast forward, to June 3rd my hubby and I got busy and the 4th I woke up and was spotting and just chalked it up to being “too rough” and I just ended my period so it’s probably just left over. But I spotted for 3 whole days but didn’t have to wear anything. Then June 9th we went to Busch gardens and every single roller coaster minus the log rides I got woozy and felt like I was gonna pass out/black out which is weird because my whole life I have never felt that and always loved roller coasters. Well yesterday, the 11th I was cleaning up and just felt extra fat/bloated and something just crossed my mind to take a test since the whole roller coaster thing. Well it was a big fat dark positive and now I’m just confused on how to calculate how far along I am or what I need to tell the doctors office to schedule my first appt. So any advise is welcome 😅
