Yes absolutely! My son is 2yo now, but I was so stressed when we were trying to conceive. I made us take those do it yourself fertility tests (useless by the way, do not waste your money), I tracked every second of my cycle (including temperature) and I stressed about how long it would take.
Then I fell pregnant within 4 months. So I felt a bit silly afterwards for stressing so much.
If trying to time sex to your ovulation cycle is stressful I wouldn't worry about it. Your body is amazing and can actually fall pregnant no matter what time of the cycle you have sex. Also your ovulation/conception window is bigger than you might think so your probably already hitting it!
I felt anxious throughout my pregnancy as well. I was more worried about the birth than anything else. I planned exactly what would happen and did birthing classes etc, then in the end none of it mattered.
It is important to keep a close eye on your mental health after baby comes. If you have a history of depression or anxiety you can be at a higher risk of postnatal issues (like I was), but if you keep in regular contact with your support people / GP, they will help you identify it and take action as early as possible.
I hope you are able to enjoy your pregnancy a little once you get there. Yes it can be hard and painful and just exhausting, but it is also amazing and exhilarating and very special.
