Same situation

Okay- I had a Mc at 16 weeks in April. My husband and I have been trying to conceive since then and have had no luck. Now my husband is back in the oilfield and is literally on the opposite side of Texas right now. He is doing 6 on 2 off. So as of now when he comes home I’m not fertile. We have a daughter who is 6. I almost don’t want to have more kids if she is going to be 7. I hate huge age gaps-my sister and I have a 6 year age gap and even with that we did not get along until just recently. I’m 23 and she’s 17-sometimes we still struggle to. I don’t want a huge age gap for my kids. I feel at this point we won’t be having anymore. Anyone else in this situation? I’ve almost considered doing IVF or something with my husband since he is never home.
