Explained below

Detailed Answer:
Hello
Thanks for writing to us with your health concern.
Since you have a 25 day cycle, ovulation is likely to occur on day 11 - day 12.
So it is possible that you ovulated around the 31st of July, and that is when fertilization / conception occurred.
Please get an ultrasound scan done to confirm the days of pregnancy.
Then you can go for MTP using medical pills.
I will explain the procedure to you.
First and foremost, medical abortion should NOT be attempted without medical supervision.
1. Even if the home pregnancy test is positive, the pregnancy needs to be confirmed by a gynecologist and exact dating needs to be done, since these pills work only up to specific gestational age, and not beyond that.
2. You need to rule out possibility of ectopic pregnancy (pregnancy outside the uterus) which will also be done by a specialist, as taking medical pills in that scenario is disastrous and life threatening.
3. Medical abortion has also got chances of severe life threatening bleeding at times, for which you need to be under medical care.
4. It has a 5 % failure rate, following which you require surgical termination, which might be needed in an emergency also.
5. Unsupervised medical abortion might cause severe infection, retained products which maybe undetected. Hence it is important to have a follow up visit with your gynecologist two weeks AFTER taking the pills, at which it would be confirmed that the pregnancy was successfully and completely terminated.

That said and done, I would give you a few guidelines about medical termination: Each pack contains 5 tablets -
1 tablet of Mifepristone…200 mg
4 tablets of Misoprostol, each containing Misoprostol…200 mcg

Mifipristone is taken orally and 1–3 days later by 800 mg of misoprostol is administered vaginally either by the clinician or self-administered.

For women at 49–63 days of gestation, if abortion has not occurred 4 hours after administration of misoprostol, a second dose of misoprostol 400 mcg may be administered vaginally or orally (depending upon preference and amount of bleeding).

The patient should return for a follow-up visit approximately 14 days after the administration of mifepristone. This visit is very important to confirm by clinical examination or ultrasonographic scan that a complete termination of pregnancy has occurred.

Patients who have an ongoing pregnancy at this visit have a risk of foetal malformation resulting from the treatment. Surgical termination is recommended to manage medical abortion treatment failures
Also, the dose might vary depending on body weight or other risk factors present in the patient, so as stressed by me earlier, please go for this procedure ONLY AFTER consultation, and examination by a specialist; else you place the person undergoing this at great risk

I hope this information encourages you to consult your doctor. I will be available for further guidance.
All the best
Please feel free to discuss further.

Brief Answer:
No effect on future fertility as such.

Detailed Answer:
Hi again.
As such, abortion with medical pills does not lead to any long term problems.
There is a 4 % chance of complications such as failure of abortion, infection, adhesions etc which might complicate future pregnancy.
Since you are 34, and the older child is grown up, if you wish to have a second child, this is the best time.
