TTC after miscarriage/chemical

Logan

Hello! I had my first miscarriage last month following 2 healthy term pregnancies (3 yo and 18 mo old). I think it could have been a chemical as I was only around 5 weeks (apparently — not positive on dates, that is what I was told during US when I started bleeding). Started bleeding 9/17, bled for 1 week similar to a normal period and was cleared to start trying again after blood work around 9/24. Now technically on “CD 40” based on day one of miscarriage and still no period. I have had very very light brown spotting/discharge for the last 4 days. Pregnancy tests all negative (testing with FRER 1st thing in am) Thoughts??

To add - I got pregnant in 1 cycle all three times previously. My cycles are typically longer around 34-36 days. Also still breastfeeding my 18 mo 1-2 x/day and only had 2 periods in July and August this year before conceiving and only 1 period in between baby 1 and 2 so not a lot of info on what a “normal” cycle is for me.

Help 😊
