Answer

To solve the question "If pregnancy occurs after ovulation then:", we need to analyze the options provided and understand the physiological changes that occur in the female body during pregnancy.

### Step-by-Step Solution:

1. **Understanding Ovulation and Pregnancy**:
- Ovulation is the release of an egg from the ovary. If fertilization occurs after ovulation, it can lead to pregnancy.

2. **Analyzing the Role of Progesterone**:
- After ovulation, the ruptured follicle transforms into the corpus luteum, which secretes progesterone. Progesterone is crucial for maintaining the uterine lining (endometrium) and supporting early pregnancy.

3. **Evaluating the Options**:
- **Option A**: "Progesterone level raises in blood" - This is correct as progesterone levels increase to prepare the uterus for a potential pregnancy.
- **Option B**: "Secretion of FSH alleged increase" - This is incorrect. Follicle Stimulating Hormone (FSH) levels do not increase during pregnancy; they actually decrease.
- **Option C**: "Corpus albicans convert corpus luteum" - This is incorrect. The corpus luteum forms after ovulation and can only convert to corpus albicans if pregnancy does not occur.
- **Option D**: "All of the above" - This is incorrect since not all statements are true.

4. **Conclusion**:
- The correct answer is **Option A**: "Progesterone level raises in blood".

### Final Answer:
If pregnancy occurs after ovulation, then the progesterone level raises in blood.
