Worried about womb lining and TTC

[sizethree]

Hi, I'm looking for some advice on light periods after pregnancy.
I didn't have a period for over a year after the birth of my daughter and I visited an osteopath who magically kick started my cycle again and I've now had 4 periods in the past 4 months.
But now they are much closer together than before (I used to have a super regular 28 day cycle) and they now vary from 23-28 days and only last for around 3 days instead of 5 to 7.
I've suffered from recurrent Miscarriage and I'm terribly worried that my light womb lining will be useless when TTC this time as it's so different from before.
My GP doesn't think I need to worry but I am.
Is this normal after a successful pregnancy and birth? And I'm still breastfeeding once a day at bedtime which could maybe affect my cycle?
Any advice would be so appreciated. I'm keen to TTC but terrified in equal measure.

Different situation but I had a very thin line womb lining after 10 years with a mirena. Had trouble conceiving my first child and had a scan that confirmed it. I had acupuncture and used Chinese medicine to thicken it up after seeing a Chinese doctor. Could have been conincidence but I got pregnant that month after 7 previous months ttc.

Have you ever been checked for Asherman's Syndrome? The main symptoms are lighter periods and recurrent miscarriages and are mostly caused by d&c's

Thank you both for your replies. I've not heard of Ashermans Syndrome so shall look into that, and the Chinese herbal medicine. I'm so hoping it will be possible for me to have a other baby and to have a smoother journey.

Not the same exactly but I was worried that my periods were too watery and maybe my lining wasn't thick enough so I wasn't getting my BFP. I ready good things about raspberry leaf tea so I tried it. Got my BFP that month (now 6 + 3)
