Will I ever conceive? 3 recurrent loses in a row

[2020wish]

I’m 31, partner 35. We both have children from previous relationships. My daughter is 9 and his youngest is 7(he has 4 in total) ... so I didn’t think we would struggle to conceive.

Been trying since December.. positive pregnancy test 13dpo in jan but resulted in chemical as af showed few days later. BFP again 14dpo in March- miscarriage around 7 weeks in April just last. Got another BFP 10dpo beginning of this week and positive early clear blue digital on 11dpo. But sadly I think I’m having another chemical (3 digitals all negative today, 2 manual early response still positive)

Af is due tomorrow or Tuesday based on my last mc bleed and ovulation on 11th may.

I feel so depressed and deflated over this... we pushed our wedding back a year to start ttc and now I’m feeling we are running out of time and may have to give up.

Anyone else had recurring loses like this and went on to have a good outcome? Why does this keep happening? I haven’t been seen by anyone for investigations due to covid. I feel it’s pointless even trying anymore as how am I meant to enjoy any pregnancy always thinking the worst is going to happen

Any help would be much appreciated

So far I’ve had no health conditions and I’m on no medications at all. They have taken my bloods to investigate so depending on what shows on those results I’m hoping I’m fine to take a low dose. At this point I think I’m willing to try anything
